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         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   -!- 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}.
