General annotation (Comments)

Function

Involved in the biosynthesis of lipid A, a phosphorylated glycolipid that anchors the lipopolysaccharide to the outer membrane of the cell By similarity. HAMAP-Rule MF_00387

Catalytic activity

(R)-3-hydroxytetradecanoyl-[acyl-carrier-protein] + UDP-N-acetyl-alpha-D-glucosamine = [acyl-carrier-protein] + UDP-3-O-(3-hydroxytetradecanoyl)-N-acetyl-alpha-D-glucosamine. HAMAP-Rule MF_00387

Pathway

Glycolipid biosynthesis; lipid IV(A) biosynthesis; lipid IV(A) from (3R)-3-hydroxytetradecanoyl-[acyl-carrier-protein] and UDP-N-acetyl-alpha-D-glucosamine: step 1/6. HAMAP-Rule MF_00387

Subunit structure

Homotrimer By similarity. HAMAP-Rule MF_00387

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_00387.

Sequence similarities

Belongs to the transferase hexapeptide repeat family. LpxA subfamily.
