Sysname
phosphatidylcholine:sterol O-acyltransferase
Reaction(IUBMB)
phosphatidylcholine + a sterol = 1-acylglycerophosphocholine + a sterol ester [RN:
R02114 ]
Reaction(KEGG)
Substrate
Product
1-acylglycerophosphocholine [CPD:
C04230 ];
sterol ester [CPD:
C01958 ]
Comment
Palmitoyl, oleoyl and linoleoyl residues can be transferred; a number of sterols, including cholesterol, can act as acceptors. The bacterial enzyme also catalyses the reactions of EC
3.1.1.4 phospholipase A2 and EC
3.1.1.5 lysophospholipase.
History
EC 2.3.1.43 created 1972, modified 1976
Pathway
ec00564 Glycerophospholipid metabolism
Orthology
K00650 lecithin-cholesterol acyltransferase
