CC   -!- FUNCTION: Catalyzes the N-acylation of UDP-3-O-acylglucosamine using 3-
CC       hydroxyacyl-ACP as the acyl donor. Is involved in the biosynthesis of
CC       lipid A, a phosphorylated glycolipid that anchors the
CC       lipopolysaccharide to the outer membrane of the cell.
CC       {ECO:0000255|HAMAP-Rule:MF_00523}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a (3R)-hydroxyacyl-[ACP] + a UDP-3-O-[(3R)-3-hydroxyacyl]-
CC         alpha-D-glucosamine = a UDP-2-N,3-O-bis[(3R)-3-hydroxyacyl]-alpha-D-
CC         glucosamine + H(+) + holo-[ACP]; Xref=Rhea:RHEA:53836, Rhea:RHEA-
CC         COMP:9685, Rhea:RHEA-COMP:9945, ChEBI:CHEBI:15378, ChEBI:CHEBI:64479,
CC         ChEBI:CHEBI:78827, ChEBI:CHEBI:137740, ChEBI:CHEBI:137748;
CC         EC=2.3.1.191; Evidence={ECO:0000255|HAMAP-Rule:MF_00523};
CC   -!- PATHWAY: Bacterial outer membrane biogenesis; LPS lipid A biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_00523}.
CC   -!- SUBUNIT: Homotrimer. {ECO:0000255|HAMAP-Rule:MF_00523}.
CC   -!- SIMILARITY: Belongs to the transferase hexapeptide repeat family. LpxD
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_00523}.
