WebMay 5, 2024 · The E. coli fatty acid synthase gene was introduced into several genetic backgrounds of the yeast Y. lipolytica to optimize lipid synthesis; the mean cyclopropane fatty acid productivity was 43 mg L−1 h−1 on glucose, and the production rate reached its maximum (3.06 g L−1) after 72 h of cultivation in a bioreactor. WebMay 11, 2011 · Cyclopropane fatty acids (CFAs) are synthetized in situ by the transfer of a methylene group from S-adenosyl-l-methionine to a double bond of unsaturated fatty acid chains of membrane phospholipids.This conversion, catalyzed by the Cfa synthase enzyme, occurs in many bacteria and is recognized to play a key role in the adaptation of …
WebDec 19, 2002 · Cyclopropane fatty acids (CFAs) are a major component of the phospholipids of many species of bacteria (Grogan and Cronan, 1997). These acids are formed by addition of a methylene group, derived from the methyl group of S-adenosyl methionine, across the carbon–carbon double bond of unsaturated fatty acids (UFAs) … WebBradley S. Moore, Heinz G. Floss, in Comprehensive Natural Products Chemistry, 1999 1.03.2.2.2 Enzymes and encoding genes. Cyclopropane fatty acid (CFA) synthase was discovered in 1963 by Zalkin et al. 28 The enzyme from E. coli has since been extensively studied by Cronan and co-workers.

WebMar 12, 2024 · In this work, we studied in vitro the effect of the thiourea drug isoxyl on six epoxide hydrolases of M. tuberculosis using a fatty acid substrate. We show that one of the proteins inhibited by isoxyl is EphD, an enzyme involved in the metabolism of mycolic acids, key components of the mycobacterial cell wall. CPAs are derived from unsaturated fatty acids by cyclopropanation. The methylene donor is a methyl group on S-adenosylmethionine (SAM). The conversion is catalyzed by cyclopropane-fatty-acyl-phospholipid synthase. The mechanism is proposed to involve transfer of a CH3 group from SAM to the alkene, followed by deprotonation of the newly attached methyl group and ring closure.
