CC -!- FUNCTION: Catalyzes the N-acylation of UDP-3-O-
CC (hydroxytetradecanoyl)glucosamine using 3-hydroxytetradecanoyl-ACP as
CC the acyl donor. Is involved in the biosynthesis of lipid A, a
CC phosphorylated glycolipid that anchors the lipopolysaccharide to the
CC outer membrane of the cell. {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 -!- CATALYTIC ACTIVITY:
CC Reaction=(3R)-hydroxytetradecanoyl-[ACP] + UDP-3-O-[(3R)-3-
CC hydroxytetradecanoyl]-alpha-D-glucosamine = H(+) + holo-[ACP] + UDP-
CC 2-N,3-O-bis[(3R)-3-hydroxytetradecanoyl]-alpha-D-glucosamine;

CC ChEBI:CHEBI:78474, ChEBI:CHEBI:78847; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00523};
CC -!- PATHWAY: Glycolipid biosynthesis; lipid IV(A) biosynthesis; lipid IV(A)
CC from (3R)-3-hydroxytetradecanoyl-[acyl-carrier-protein] and UDP-N-
CC acetyl-alpha-D-glucosamine: step 3/6. {ECO:0000255|HAMAP-
CC 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}.
