Zhang, Wei;Tang, Weng Lin;Wang, Zunsheng;Li, Zhi research published 《 Regio- and Stereoselective Biohydroxylations with a Recombinant Escherichia coli Expressing P450_pyr Monooxygenase of Sphingomonas Sp. HXN-200》, the research content is summarized as follows. A recombinant Escherichia coli expressing P 450_pyr monooxygenase of Sphingomonas sp HXN-200 was developed as a useful biocatalyst for regio- and stereoselective hydroxylations, with no side reaction and easy cell growth. The resting E. coli cells showed an activity of 4.1 U/g cdw and 9.9 U/g cdw for the hydroxylation of N-benzylpyrrolidin-2-one and N-benzyloxycarbonylpyrrolidine, resp., being as active as the wide-type strain. Biohydroxylation of N-benzylpyrrolidin-2-one 1 with the resting cells gave (S)-N-benzyl-4-hydroxypyrrolidin-2-one in >99% ee and 10.8 mM, a 2.6 times increase of product concentration in comparison with the wild-type strain. Biohydroxylation of N-tert-butoxycarbonylpiperidin-2-one, N-benzylpiperidine and N-tert-butoxycarbonylazetidine with the E. coli cells afforded the corresponding 4-hydroxypiperidin-2-one, 4-hydroxypiperidine, and 3-hydroxyazetidine in 14 mM, 17 mM, and 21 mM, resp. Moreover, hydroxylation of (-)-β-pinene with the recombinant E. coli cells showed excellent regio- and stereoselectivity and gave (1R)-trans-pinocarveol in 82% yield and 4.1 mM, which is over 200 times higher than that obtained with the best biocatalytic system known thus far. The recombinant strain was also able to hydroxylate other types of substrates with unique selectivity: biohydroxylation of norbornane gave exo-norbornaeol, with exo/endo selectivity of 95%; tetralin and 6-methoxytetralin were hydroxylated at the non-activated 2-position, for the first time, with regioselectivities of 83-84%.

Zhang, Mengxue;Zhao, Xingcong;Chen, Xi;Li, Mingyue;Wang, Xuedong research published 《 Enhancement of riboflavin production in Bacillus subtilis via in vitro and in vivo metabolic engineering of pentose phosphate pathway》, the research content is summarized as follows. The production of riboflavin with Bacillus subtilis, is an established process, however it is yet to be fully optimized. The aim of this study was to explore how riboflavin yields can be improved via in vitro and in vivo metabolic engineering modification of the pentose phosphate pathway (PPP). In vitro, glucose was replaced with sodium gluconate to enhance PPP. Flask tests showed that the riboflavin titer increased from 0.64 to 0.87 g/L. The results revealed that the direct use of sodium gluconate could benefit riboflavin production In vivo, gntP (encoding gluconate permease) was overexpressed to improve sodium gluconate uptake. The riboflavin titer reached 1.00 g/L with the mutant B. subtilis RF01. Ultimately, the fermentation verification of the engineered strain was carried out in a 7-L fermenter, with the increased riboflavin titer validating this approach. The combination of metabolic engineering modifications in vitro and in vivo was confirmed to promote riboflavin production efficiently by increasing PPP and has great potential for industrial application. This work is aimed to explore how to improve the riboflavin yield by the rational renovation of the pentose phosphate pathway (PPP). In vitro, metabolic engineering mainly uses sodium gluconate as a carbon source instead of glucose, and in vivo, metabolic engineering mainly includes the overexpression of sodium gluconate utility-related genes. The effect of sodium gluconate on cell growth, riboflavin production was investigated in the flasks and fermenter scale.
