ID 2.3.1.149 DE platelet-activating factor acetyltransferase. AN PAF acetyltransferase. CA a 1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine + a 1-organyl-2-lyso- CA sn-glycero-3-phospholipid = 1-O-alkyl-sn-glycero-3-phosphocholine + CA a 1-organyl-2-acetyl-sn-glycero-3-phospholipid. CC -!- Catalyzes the transfer of the acetyl group from 1-alkyl-2-acyl- CC sn-glycero-3-phosphocholine (platelet-activating factor) to the sn-2 CC position of lyso-glycerophospholipids containing ethanolamine, CC choline, serine, inositol or phosphate groups at the sn-3 position as CC well as to sphingosine and long-chain fatty alcohols. CC -!- The organyl group can be alkyl, acyl or alk-1-enyl (sometimes also CC collectively referred to as 'radyl').
