Cyclopropane fatty acid synthase
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. WebThe cyclopropane fatty acids have similar biophysical properties to the UFAs, but render the membrane more stable to environmental insults, …
