IntEnz Enzyme Nomenclature


Accepted name:
methylene-fatty-acyl-phospholipid synthase
Other name:
unsaturated-phospholipid methyltransferase
Systematic name:
S-adenosyl-L-methionine:unsaturated-phospholipid methyltransferase (methenylating)



The enzyme transfers a methyl group to the 10-position of a Δ-olefinic acyl chain in phosphatidylglycerol or phosphatidylinositol or, more slowly, phosphatidylethanolamine; subsequent proton transfer produces a 10-methylene group (cf. EC cyclopropane-fatty-acyl-phospholipid synthase).
