Functional Family Lipid A palmitoyltransferase PagP

Enzyme Information

2.3.1.251
Lipid IV(A) palmitoyltransferase.
based on mapping to UniProt P37001
(1) 1-palmitoyl-2-acyl-sn-glycero-3-phosphocholine + hexa-acyl lipid A = 2-acyl-sn-glycero-3-phosphocholine + hepta-acyl lipid A. (2) 1-palmitoyl-2-acyl-sn-glycero-3-phosphocholine + lipid II(A) = 2-acyl-sn-glycero-3-phosphocholine + lipid II(B). (3) 1-palmitoyl-2-acyl-sn-glycero-3-phosphocholine + lipid IV(A) = 2-acyl-sn-glycero-3-phosphocholine + lipid IV(B).
-!- Isolated from the bacteria Escherichia coli and Salmonella typhimurium. -!- The enzyme prefers phosphatidylcholine with a palmitoyl group at the sn-1 position and palmitoyl or stearoyl groups at the sn-2 position. -!- There is some activity with corresponding phosphatidylserines but only weak activity with other diacylphosphatidyl compounds. -!- The enzyme also acts on Kdo-(2->4)-Kdo-(2->6)-lipid IV(A).
