Glycerophospholipid acyltransferase (CoA-dependent)

Thus, the two substrates of this enzyme are 1-organyl-2-acyl-sn-glycero-3-phosphocholine and 1-organyl-2-lyso-sn-glycero-3-phosphoethanolamine, whereas its two products are 1-organyl-2-acyl-sn-glycero-3-phosphoethanolamine and 1-organyl-2-lyso-sn-glycero-3-phosphocholine.

This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is 1-organyl-2-acyl-sn-glycero-3-phosphocholine:1-organyl-2-lyso-sn-gly cero-3-phosphoethanolamine acyltransferase (CoA-dependent).
