Enzyme Information

2.1.1.79

Cyclopropane-fatty-acyl-phospholipid synthase.

based on mapping to UniProt P9WPB5

S-adenosyl-L-methionine + phospholipid olefinic fatty acid = S-adenosyl- L-homocysteine + phospholipid cyclopropane fatty acid.

-!- Adds a methylene group across the 9,10 position of a Delta(9)- olefinic acyl chain in phosphatidylethanolamine or, more slowly, phosphatidylglycerol or phosphatidylinositol forming a cyclopropane derivative (cf. EC 2.1.1.16).
