RC STRAIN=541-15 {ECO:0000313|EMBL:EIL50394.1, RC ECO:0000313|Proteomes:UP000004544}; RA Suzuki H., Richards V., Lefebure T., Pavinski Bitar P., Lang P., RA Stanhope M.; RL Submitted (APR-2010) to the EMBL/GenBank/DDBJ databases. 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 + 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 Evidence={ECO:0000256|ARBA:ARBA00000183, 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 inner membrane CC {ECO:0000256|RuleBase:RU365103}. CC -!- SIMILARITY: Belongs to the glycosyltransferase group 1 family. CC {ECO:0000256|RuleBase:RU365103}. CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ CC whole genome shotgun (WGS) entry which is preliminary data. CC {ECO:0000313|EMBL:EIL50394.1}.
