Cyclopropane-fatty-acyl-phospholipid

WebJan 27, 2024 · Phospholipid fatty acid analysis showed that H. socia cultured under high osmotic pressure produced a high portion of cyclopropane fatty acid derivatives, encoded by the cyclopropane-fatty acid-acyl phospholipid synthase gene ( cfa ). Therefore, H. socia cfa was cloned and introduced into Escherichia coli for expression. 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.
