[[http://www.uniprot.org/uniprot/CRCA_ECOLI CRCA_ECOLI]] PagP is required both for biosynthesis of hepta-acylated lipid A species containing palmitate and for resistance to cationic antimicrobial peptides (CAMPs). It catalyzes the transfer of a palmitate chain (16:0) from the sn-1 position of a glycerophospholipid to the free hydroxyl group of the (R)-3-hydroxymyristate chain at position 2 of lipid A (endotoxin). Modifications of lipid A with a palmitate chain allow to evade host immune defenses by resisting antimicrobial peptides and attenuating the inflammatory response to infection triggered by lipopolysaccharide through the Toll-like receptor 4 (TLR4) signal transduction pathway. Phosphatidylglycerol (PtdGro), phosphatidylethanolamine (PtdEtn), phosphatidylserine (PtdSer) and phosphatidic acid (Ptd-OH) are all effective acyl donors.<ref>PMID:11013210</ref> | |||
