case <OC:Escherichia>
FUNCTIONTransfers a palmitate residue from the sn-1 position of a phospholipid to the N-linked hydroxymyristate on the proximal unit of lipid A or its precursors.
CATALYTIC ACTIVITY Reaction=lipid A (E. coli) + a 1-hexadecanoyl-2-acyl-sn-glycero-3- phosphocholine = hepta-acyl lipid A (E. coli) + a 2-acyl-sn-glycero- 3-phosphocholine; Xref=Rhea:RHEA:46864, ChEBI:CHEBI:57875, ChEBI:CHEBI:77369, ChEBI:CHEBI:87048, ChEBI:CHEBI:134257; EC=2.3.1.251;
CATALYTIC ACTIVITY Reaction=lipid IIA + a 1-hexadecanoyl-2-acyl-sn-glycero-3- phosphocholine = lipid IIB + a 2-acyl-sn-glycero-3-phosphocholine; Xref=Rhea:RHEA:46872, ChEBI:CHEBI:57875, ChEBI:CHEBI:77369, ChEBI:CHEBI:86226, ChEBI:CHEBI:87058; EC=2.3.1.251;
