And the article was included in Nature Communications in 2021.Recommanded Product: (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol The following contents are mentioned in the article:

Purple coneflower (Echinacea purpurea (L.) Moench) is a popular native North American herbal plant. Its major bioactive compound, chicoric acid, is reported to have various potential physiol. functions, but little is known about its biosynthesis. Here, taking an activity-guided approach, we identify two cytosolic BAHD acyltransferases that form two intermediates, caftaric acid and chlorogenic acid. Surprisingly, a unique serine carboxypeptidase-like acyltransferase uses chlorogenic acid as its acyl donor and caftaric acid as its acyl acceptor to produce chicoric acid in vacuoles, which has evolved its acyl donor specificity from the better-known 1-O-β-D-glucose esters typical for this specific type of acyltransferase to chlorogenic acid. This unusual pathway seems unique to Echinacea species suggesting convergent evolution of chicoric acid biosynthesis. Using these identified acyltransferases, we have reconstituted chicoric acid biosynthesis in tobacco. Our results emphasize the flexibility of acyltransferases and their roles in the evolution of specialized metabolism in plants. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1Recommanded Product: (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol).

(2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Recommanded Product: (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol

Genetic and bioprocess engineering for the selective and high-level production of geranyl acetate in Escherichia coli was written by Wang, Xun;Zhang, Xinyi;Zhang, Jia;Xiao, Longjie;Zhou, Yujunjie;Zhang, Yu;Wang, Fei;Li, Xun. And the article was included in ACS Sustainable Chemistry & Engineering in 2022.Related Products of 367-93-1 The following contents are mentioned in the article:

Geranyl acetate is, as one of the monoterpenoids, a natural constituent of more than 60 essential oils. Production of such an ester fragrance compound by plant extracts is limited by low yield and high processing costs but plausible by microbial synthesis. We report a microbial cell factory that realizes selective and high-level geranyl acetate production in Escherichia coli. For this purpose, co-expression of geraniol synthase and alc. acetyltransferase was initially used to increase production yield, but a considerable quantity of precursor geraniol was also produced. Further, introducing an extra AAT gene copy and controlling the substrate glycerol supply enabled a drastically higher selective geranyl acetate production Eventually, the highest reported titer of 52.78 mM (equivalent to 10.36 g/L) geranyl acetate, accounting for 98.5% of total products, was achieved under a controlled fermentation system. Such selective and high-level geranyl acetate production by combining genetic and bioprocess engineering is also a promising strategy for other monoterpene esters in E. coli. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1Related Products of 367-93-1).

(2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Related Products of 367-93-1

Development of a ligand for in vivo imaging of mutant huntingtin in Huntington’s disease was written by Bertoglio, Daniele;Bard, Jonathan;Hessmann, Manuela;Liu, Longbin;Gartner, Annette;De Lombaerde, Stef;Huscher, Britta;Zajicek, Franziska;Miranda, Alan;Peters, Finn;Herrmann, Frank;Schaertl, Sabine;Vasilkovska, Tamara;Brown, Christopher J.;Johnson, Peter D.;Prime, Michael E.;Mills, Matthew R.;Van der Linden, Annemie;Mrzljak, Ladislav;Khetarpal, Vinod;Wang, Yuchuan;Marchionini, Deanna M.;Skinbjerg, Mette;Verhaeghe, Jeroen;Dominguez, Celia;Staelens, Steven;Munoz-Sanjuan, Ignacio. And the article was included in Science Translational Medicine in 2022.COA of Formula: C9H18O5S The following contents are mentioned in the article:

Huntington’s disease (HD) is a dominantly inherited neurodegenerative disorder caused by a CAG trinucleotide expansion in the huntingtin (HTT) gene that encodes the pathol. mutant HTT (mHTT) protein with an expanded polyglutamine (polyQ) tract. Whereas several therapeutic programs targeting mHTT expression have advanced to clin. evaluation, methods to visualize mHTT protein species in the living brain are lacking. Here, we demonstrate the development and characterization of a positron emission tomog. (PET) imaging radioligand with high affinity and selectivity for mHTT aggregates. This small mol. radiolabeled with 11C ([11C]CHDI-180R) allowed noninvasive monitoring of mHTT pathol. in the brain and could track region- and time-dependent suppression of mHTT in response to therapeutic interventions targeting mHTT expression in a rodent model. We further showed that in these animals, therapeutic agents that lowered mHTT in the striatum had a functional restorative effect that could be measured by preservation of striatal imaging markers, enabling a translational path to assess the functional effect of mHTT lowering. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1COA of Formula: C9H18O5S).

The NMR structure of the engineered halophilic DnaE intein for segmental isotopic labeling using conditional protein splicing was written by Heikkinen, Harri A.;Aranko, A. Sesilja;Iwai, Hideo. And the article was included in Journal of Magnetic Resonance in 2022.Formula: C9H18O5S The following contents are mentioned in the article:

Protein trans-splicing catalyzed by split inteins has been used for segmental isotopic labeling of proteins for alleviating the complexity of NMR signals. Whereas inteins spontaneously trigger protein splicing upon protein folding, inteins from extremely halophilic organisms require a high salinity condition to induce protein splicing. We designed and created a salt-inducible intein from the widely used DnaE intein from Nostoc punctiforme by introducing 29 mutations, which required a lower salt concentration than naturally occurring halo-obligate inteins. We determined the NMR solution structure of the engineered salt-inducible DnaE intein in 2 M NaCl, showing the essentially identical three-dimensional structure to the original one, albeit it unfolds without salts. The NMR structure of a halo-obligate intein under high salinity suggests that the stabilization of the active folded conformation is not a mere result of various intramol. interactions but the subtle energy balance from the complex interactions, including the solvation energy, which involve waters, ions, co-solutes, and protein polypeptide chains. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1Formula: C9H18O5S).

Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.Formula: C9H18O5S

Cellular Computational Logic Using Toehold Switches was written by Choi, Seungdo;Lee, Geonhu;Kim, Jongmin. And the article was included in International Journal of Molecular Sciences in 2022.Electric Literature of C9H18O5S The following contents are mentioned in the article:

The development of computational logic that carries programmable and predictable features is one of the key requirements for next-generation synthetic biol. devices. Despite considerable progress, the construction of synthetic biol. arithmetic logic units presents numerous challenges. In this paper, utilizing the unique advantages of RNA mols. in building complex logic circuits in the cellular environment, we demonstrate the RNA-only bitwise logical operation of XOR gates and basic arithmetic operations, including a half adder, a half subtractor, and a Feynman gate, in Escherichia coli. Specifically, de-novo-designed riboregulators, known as toehold switches, were concatenated to enhance the functionality of an OR gate, and a previously utilized antisense RNA strategy was further optimized to construct orthogonal NIMPLY gates. These optimized synthetic logic gates were able to be seamlessly integrated to achieve final arithmetic operations on small mol. inputs in cells. Toehold-switch-based ribocomputing devices may provide a fundamental basis for synthetic RNA-based arithmetic logic units or higher-order systems in cells.

Identification and Characterization of a New Type of Holin-Endolysin Lysis Cassette in Acidovorax oryzae Phage AP1 was written by Zhang, Muchen;Wang, Yanli;Chen, Jie;Hong, Xianxian;Xu, Xinyan;Wu, Zhifeng;Ahmed, Temoor;Loh, Belinda;Leptihn, Sebastian;Hassan, Sabry;Hassan, Mohamed M.;Sun, Guochang;Li, Bin. And the article was included in Viruses in 2022.Related Products of 367-93-1 The following contents are mentioned in the article:

Phages utilize lysis systems to allow the release of newly assembled viral particles that kill the bacterial host. This is also the case for phage AP1, which infects the rice pathogen Acidovorax oryzae. However, how lysis occurs on a mol. level is currently unknown. We performed in silico bioinformatics analyses, which indicated that the lysis cassette contains a holin (HolAP) and endolysin (LysAP), which are encoded by two adjacent genes. Recombinant expression of LysAP caused Escherichia coli lysis, while HolAP arrested growth. Co-expression of both proteins resulted in enhanced lysis activity compared to the individual proteins alone. Interestingly, LysAP contains a C-terminal region transmembrane domain, which is different from most known endolysins where a N-terminal hydrophobic region is found, with the potential to insert into the membrane. We show that the C-terminal transmembrane domain is crucial for protein localization and bacterial lysis in phage AP1. Our study characterizes the new phage lysis cassette and the mechanism to induce cell disruption, giving new insight in the understanding of phage life cycles. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1Related Products of 367-93-1).

Multiplexed characterization of rationally designed promoter architectures deconstructs combinatorial logic for IPTG-inducible systems was written by Yu, Timothy C.;Liu, Winnie L.;Brinck, Marcia S.;Davis, Jessica E.;Shek, Jeremy;Bower, Grace;Einav, Tal;Insigne, Kimberly D.;Phillips, Rob;Kosuri, Sriram;Urtecho, Guillaume. And the article was included in Nature Communications in 2021.Formula: C9H18O5S The following contents are mentioned in the article:

A crucial step towards engineering biol. systems is the ability to precisely tune the genetic response to environmental stimuli. In the case of Escherichia coli inducible promoters, our incomplete understanding of the relationship between sequence composition and gene expression hinders our ability to predictably control transcriptional responses. Here, we profile the expression dynamics of 8269 rationally designed, IPTG-inducible promoters that collectively explore the individual and combinatorial effects of RNA polymerase and LacI repressor binding site strengths. We then fit a statistical mechanics model to measured expression that accurately models gene expression and reveals properties of theor. optimal inducible promoters. Furthermore, we characterize three alternative promoter architectures and show that repositioning binding sites within promoters influences the types of combinatorial effects observed between promoter elements. In total, this approach enables us to deconstruct relationships between inducible promoter elements and discover practical insights for engineering inducible promoters with desirable characteristics.

Chemical denaturants induced folding unfolding pathway of the recombinant zebrafish dihydrofolate reductase was written by Acharya, Vaishali V.;Verma, Anita Kamra;Chaudhuri, Pratima. And the article was included in Indian Journal of Biochemistry & Biophysics in 2022.Related Products of 367-93-1 The following contents are mentioned in the article:

Denaturation of proteins plays a crucial part in cellular activities. In this study, we have investigated the folding unfolding pathways of zebrafish dihydrofolate reductase (zDHFR) in presence of different chem. denaturants which were found to be an influential factor for the refolding yield by UV-visible spectrophotometric anal. The activity change of zDHFR has been observed in presence of three different denaturants like Acetic Acid (AcOH), Sodium Dodecyl Sulfate (SDS), and Ethanol (C2H5OH). Spectrophotometric anal. reveals that protein unfolded completely at different concentrations and times by these denaturants. The spontaneous refolding experiments of chem. denatured zDHFR were also conducted to verify the spontaneous refolding yield. These investigations have helped us to decipher a picture about the denaturants contributing to achieving the refolding yield. We observed that acetic acid is a stronger denaturant among all, and the spontaneous refolding yields were higher from SDS denaturation. In the light of the above findings, higher spontaneous refolding yields were obtained from the low concentration of denaturants.

CRISPRi-seq for genome-wide fitness quantification in bacteria was written by de Bakker, Vincent;Liu, Xue;Bravo, Afonso M.;Veening, Jan-Willem. And the article was included in Nature Protocols in 2022.Electric Literature of C9H18O5S The following contents are mentioned in the article:

CRISPR interference (CRISPRi) is a powerful tool to link essential and nonessential genes to specific phenotypes and to explore their functions. Here we describe a protocol for CRISPRi screenings to assess genome-wide gene fitness in a single sequencing step (CRISPRi-seq). We demonstrate the use of the protocol in Streptococcus pneumoniae, an important human pathogen; however, the protocol can easily be adapted for use in other organisms. The protocol includes a pipeline for single-guide RNA library design, workflows for pooled CRISPRi library construction, growth assays and sequencing steps, a read anal. tool (2FAST2Q) and instructions for fitness quantification. We describe how to make an IPTG-inducible system with small libraries that are easy to handle and cost-effective and overcome bottleneck issues, which can be a problem when using similar, transposon mutagenesis-based methods. Ultimately, the procedure yields a fitness score per single-guide RNA target for any given growth condition. A genome-wide screening can be finished in 1 wk with a constructed library. Data anal. and follow-up confirmation experiments can be completed in another 2-3 wk.

Application of bacteriophage to develop indicator for Escherichia coli detection and modulation of its biochemical reaction to improve detection ability: A proof-of-concept study was written by Choi, Inyoung;Lee, Jung-Soo;Han, Jaejoon. And the article was included in Food Control in 2022.Electric Literature of C9H18O5S The following contents are mentioned in the article:

Bacteria indicators have been widely developed but still need complicated techniques, instruments, or well-trained users. This is a proof-of-concept study to develop a straightforward and colorimetric bacterial indicator using bacteriophages (phages) as bio-receptors and simple biochem. reactions for high sensitivity. Among the various phages, phage T4 with a high specificity to Escherichia coli was used. Hydrophilic polyvinyl alc. and trehalose were used as matrix polymers, and the optimal formulation ratio was examined to enhance the phage stability in the indicator matrix. Its sensitivity and detection rate were improved by investigating the interactions between phage T4 and iso-Pr β-D-thiogalactopyranoside. The final indicator showed high sensitivity detecting up to 10 CFU/mL after 11 h, even in the food application test such as drinking water and milk samples containing different fat contents. Although some challenges remain to satisfy the regulatory requirements for bacteria in foods and be applied to various foods, the introduced simple approach can pave the way to develop indicators to detect E. coli present in real food using phages. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1Electric Literature of C9H18O5S).

Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Electric Literature of C9H18O5S
