ID   2.1.1.16
DE   methylene-fatty-acyl-phospholipid synthase.
AN   cyclopropane synthetase.
AN   unsaturated-phospholipid methyltransferase.
CA   1-acyl-2-(9Z)-enoyl-sn-glycero-3-phospholipid + S-adenosyl-L-methionine =
CA   1-acyl-2-(10-methylene)-acyl-sn-glycero-3-phospholipid + H(+) +
CA   S-adenosyl-L-homocysteine.
CC   -!- The enzyme transfers a methyl group to the 10-position of a Delta(9)-
CC       olefinic acyl chain in phosphatidylglycerol, phosphatidylinositol,
CC       or, more slowly, phosphatidylethanolamine; subsequent proton transfer
CC       produces a 10-methylene group (cf. EC 2.1.1.79).
