In enzymology, a cyclopropane-fatty-acyl-phospholipid synthase (EC 2.1.1.79) is an enzyme that catalyzes the chemical reaction Thus, the two substrates of this enzyme are S-adenosyl methionine and phospholipid olefinic fatty acid, whereas its two products are S-adenosylhomocysteine and phospholipid cyclopropane fatty acid.
This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases.
The systematic name of this enzyme class is S-adenosyl-L-methionine:unsaturated-phospholipid methyltransferase (cyclizing).
As of late 2007, 6 structures have been solved for this class of enzymes, with PDB accession codes 1KP9, 1KPG, 1KPH, 1KPI, 1L1E, and 1TPY.
