Simple alcohols are found widely in nature. Ethanol is the most prominent because it is the product of fermentation, a major energy-producing pathway. 24034-73-9, formula is C20H34O, Other simple alcohols, chiefly fusel alcohols, are formed in only trace amounts. More complex alcohols however are pervasive, as manifested in sugars, some amino acids, and fatty acids. , Formula: C20H34O
Hayat, Irfan Farabi;Plan, Manuel;Ebert, Birgitta E.;Dumsday, Geoff;Vickers, Claudia E.;Peng, Bingyin research published 《 Auxin-mediated induction of GAL promoters by conditional degradation of Mig1p improves sesquiterpene production in Saccharomyces cerevisiae with engineered acetyl-CoA synthesis》, the research content is summarized as follows. The yeast Saccharomyces cerevisiae uses the pyruvate dehydrogenase-bypass for acetyl-CoA biosynthesis. This relatively inefficient pathway limits production potential for acetyl-CoA-derived biochem. due to carbon loss and the cost of two high-energy phosphate bonds per mol. of acetyl-CoA. Here, we attempted to improve acetyl-CoA production efficiency by introducing heterologous acetylating aldehyde dehydrogenase and phosphoketolase pathways for acetyl-CoA synthesis to enhance production of the sesquiterpene trans-nerolidol. In addition, we introduced auxin-mediated degradation of the glucose-dependent repressor Mig1p to allow induced expression of GAL promoters on glucose so that production potential on glucose could be examined The novel genes that we used to reconstruct the heterologous acetyl-CoA pathways did not sufficiently complement the loss of endogenous acetyl-CoA pathways, indicating that superior heterologous enzymes are necessary to establish fully functional synthetic acetyl-CoA pathways and properly explore their potential for nerolidol synthesis. Notwithstanding this, nerolidol production was improved twofold to a titer of ∼ 900 mg l-1 in flask cultivation using a combination of heterologous acetyl-CoA pathways and Mig1p degradation Conditional Mig1p depletion is presented as a valuable strategy to improve the productivities in the strains engineered with GAL promoters-controlled pathways when growing on glucose.
24034-73-9, Geranylgeraniol is a diterpenoid that is hexadeca-2,6,10,14-tetraene substituted by methyl groups at positions 3, 7, 11 and 15 and a hydroxy group at position 1. It has a role as a plant metabolite, a volatile oil component and an antileishmanial agent. It is a diterpenoid and a polyprenol.
Geranylgeraniol, a precursor to geranylgeranylpyrophosphate, is an intermediate in the mevalonate pathway. Geranylgeraniol has been shown to prevent bone re-absorption, inhibition of osteoclast formation, and kinase activation in vitro. When working with statins, Geranylgeraniol can reduce the toxicity without inhibiting the cholesterol-producing effects. Geranylgeraniol has been documented to counteract the effects of fluvastatin by inhibiting activation of caspase-1 and production of IL-1. Additionally Geranylgeraniol has been found to induce apoptosis in HL-60 cells.
