WebCyclopropane synthase from Sterculia foetida developing seeds catalyzes the addition of a methylene group from S-adenosylmethionine to the cisdouble bond of oleic acid (Bao, X., Katz, S., Pollard, M., and Ohlrogge, J. (2002) Proc. Natl. Acad. Sci. U. S. A. 99, 7172–7177). To understand this enzyme better, differential expression in leaf and seed tissues, … WebA large structural diversity of free fatty acids (FFAs) with over 50 different n- and branched-chain, (un)saturated, and cyclopropane FAs (C7–C30) has been demonstrated. There is a strong rationale behind elucidating mechanisms for overproduction of FFA and their export to medium, since it can be exploited in microbial biodiesel production.

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) … WebThe cyclopropane fatty acids have similar biophysical properties to the UFAs, but render the membrane more stable to environmental insults, … WebBiosynthesis []. 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 CH 3 + group from SAM to the alkene, followed by deprotonation … fn hop-o\\u0027-my-thumb
