CC   -!- FUNCTION: Condensation of UDP-2,3-diacylglucosamine and 2,3-
CC       diacylglucosamine-1-phosphate to form lipid A disaccharide, a precursor
CC       of lipid A, a phosphorylated glycolipid that anchors the
CC       lipopolysaccharide to the outer membrane of the cell.
CC       {ECO:0000255|HAMAP-Rule:MF_00392}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2-N,3-O-bis(3-hydroxytetradecanoyl)-alpha-D-glucosaminyl 1-
CC         phosphate + UDP-2-N,3-O-bis[(3R)-3-hydroxytetradecanoyl]-alpha-D-
CC         glucosamine = H(+) + lipid A disaccharide (E. coli) + UDP;
CC         Xref=Rhea:RHEA:22668, ChEBI:CHEBI:15378, ChEBI:CHEBI:57957,
CC         ChEBI:CHEBI:58223, ChEBI:CHEBI:58466, ChEBI:CHEBI:78847;
CC         EC=2.4.1.182; Evidence={ECO:0000255|HAMAP-Rule:MF_00392};
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 5/6. {ECO:0000255|HAMAP-
CC       Rule:MF_00392}.
CC   -!- SIMILARITY: Belongs to the LpxB family. {ECO:0000255|HAMAP-
CC       Rule:MF_00392}.
