ENTRY       EC 2.1.1.79
NAME        Cyclopropane-fatty-acyl-phospholipid synthase
            Cyclopropane synthetase
            Unsaturated-phospholipid methyltransferase
CLASS       Transferases
            Transferring one-carbon groups
            Methyltransferases
SYSNAME     S-Adenosyl-L-methionine:unsaturated-phospholipid methyltransferase
            $ (cyclizing)
REACTION    S-Adenosyl-L-methionine + Phospholipid olefinic fatty acid =
            S-Adenosyl-L-homocysteine +
            Phospholipid cyclopropane fatty acid
SUBSTRATE   S-Adenosyl-L-methionine
            Phospholipid olefinic fatty acid
PRODUCT     S-Adenosyl-L-homocysteine
            Phospholipid cyclopropane fatty acid
COMMENT     The enzyme adds a methylene group across the 9,10 position of a
            delta9-olefinic acyl chain in phosphatidylethanolamine or, more
            slowly, phosphatidylglycerol or phosphatidylinositol forming a
            cyclopropane deirvative (cf. EC 2.1.1.16).
