Accepted name: cyclopropane-fatty-acyl-phospholipid synthase
S-adenosyl- L-methionine + phospholipid olefinic fatty acid = S-adenosyl- L-homocysteine + phospholipid cyclopropane fatty acid
Other name(s): cyclopropane synthetase; unsaturated-phospholipid methyltransferase; cyclopropane synthase; cyclopropane fatty acid synthase; cyclopropane fatty acid synthetase; CFA synthase
S-adenosyl- L-methionine:unsaturated-phospholipid methyltransferase (cyclizing)
Comments: The enzyme adds a methylene group across the 9,10 position of a Δ
-olefinic acyl chain in phosphatidylethanolamine or, more slowly, phosphatidylglycerol or phosphatidylinositol, forming a cyclopropane derivative ( 9 cf. EC 126.96.36.199 methylene-fatty-acyl-phospholipid synthase).
