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=a lipid X + a UDP-2-N,3-O-bis[(3R)-3-hydroxyacyl]-alpha-D-
CC         glucosamine = a lipid A disaccharide + H(+) + UDP;
CC         Xref=Rhea:RHEA:67828, ChEBI:CHEBI:15378, ChEBI:CHEBI:58223,
CC         ChEBI:CHEBI:137748, ChEBI:CHEBI:176338, ChEBI:CHEBI:176343;
CC         EC=2.4.1.182; Evidence={ECO:0000255|HAMAP-Rule:MF_00392};
CC   -!- PATHWAY: Bacterial outer membrane biogenesis; LPS lipid A biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_00392}.
CC   -!- SIMILARITY: Belongs to the LpxB family. {ECO:0000255|HAMAP-
CC       Rule:MF_00392}.
