Summary
Description
Possesses both acyltransferase and acetyltransferase activities (PubMed:16704971). Activity is calcium-independent (PubMed:18285344). Mediates the conversion of 1-acyl-sn-glycero-3-phosphocholine (LPC) into phosphatidylcholine (PC) (PubMed:16704971, PubMed:18156367). Displays a clear preference for saturated fatty acyl-CoAs, and 1-myristoyl or 1-palmitoyl LPC as acyl donors and acceptors, respectively (PubMed:16704971, PubMed:18285344). May synthesize phosphatidylcholine in pulmonary surfactant, thereby playing a pivotal role in respiratory physiology (PubMed:16704971). Involved in the regulation of lipid droplet number and size (By similarity).
Catalytic Activity
a 1-acyl-sn-glycero-3-phosphocholine + an acyl-CoA = a 1,2-diacyl-sn-glycero-3-phosphocholine + CoA
1-O-alkyl-sn-glycero-3-phosphocholine + acetyl-CoA = 1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine + CoA
Biophysicochemical Properties
2.3 uM for 1-palmitoyl-LPC
3 uM for palmitoyl-CoA
Similarity
Belongs to the 1-acyl-sn-glycerol-3-phosphate acyltransferase family.
