Protein attributes

Sequence length	333 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Catalyzes the N-acylation of UDP-3-O-acylglucosamine using 3-hydroxyacyl-ACP as the acyl donor. Is involved in the biosynthesis of lipid A, a phosphorylated glycolipid that anchors the lipopolysaccharide to the outer membrane of the cell By similarity. HAMAP MF_00523
Catalytic activity	(3R)-3-hydroxyacyl-[acyl-carrier-protein] + UDP-3-O-acyl-alpha-D-glucosamine = UDP-2,3-diacyl-alpha-D-glucosamine + [acyl-carrier-protein]. HAMAP MF_00523
Pathway	Bacterial outer membrane biogenesis; LPS lipid A biosynthesis. HAMAP MF_00523
Subunit structure	Homotrimer By similarity. HAMAP MF_00523
Sequence similarities	Belongs to the transferase hexapeptide repeat family. LpxD subfamily.
