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:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=CMP-3-deoxy-beta-D-manno-octulosonate + lipid IVA (E. coli) =
CC         alpha-Kdo-(2->6)-lipid IVA + CMP + H(+); Xref=Rhea:RHEA:28066,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:58603, ChEBI:CHEBI:60364,
CC         ChEBI:CHEBI:60377, ChEBI:CHEBI:85987; EC=2.4.99.12;
CC   -!- PATHWAY: Bacterial outer membrane biogenesis; LPS core biosynthesis.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Single-pass
CC       membrane protein {ECO:0000250}; Cytoplasmic side {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the glycosyltransferase group 1 family.
CC       Glycosyltransferase 30 subfamily. {ECO:0000305}.
