CC   -!- FUNCTION: Involved in lipopolysaccharide (LPS) biosynthesis. Catalyzes
CC       the transfer of 3-deoxy-D-manno-octulosonate (Kdo) residue(s) from CMP-
CC       Kdo to lipid IV(A), the tetraacyldisaccharide-1,4'-bisphosphate
CC       precursor of lipid A. {ECO:0000256|RuleBase:RU365103}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=CMP-3-deoxy-beta-D-manno-octulosonate + lipid IVA (E. coli) =
CC         alpha-Kdo-(2->6)-lipid IVA (E. coli) + CMP + H(+);
CC         Xref=Rhea:RHEA:28066, ChEBI:CHEBI:15378, ChEBI:CHEBI:58603,
CC         ChEBI:CHEBI:60364, ChEBI:CHEBI:60377, ChEBI:CHEBI:85987;
CC         EC=2.4.99.12; Evidence={ECO:0000256|ARBA:ARBA00034406,
CC         ECO:0000256|RuleBase:RU365103};
CC   -!- PATHWAY: Bacterial outer membrane biogenesis; LPS core biosynthesis.
CC       {ECO:0000256|ARBA:ARBA00004713, ECO:0000256|RuleBase:RU365103}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|RuleBase:RU365103}.
CC   -!- SIMILARITY: Belongs to the glycosyltransferase group 1 family.
CC       {ECO:0000256|RuleBase:RU365103}.
