CC -!- FUNCTION: Activates KDO (a required 8-carbon sugar) for incorporation
CC into bacterial lipopolysaccharide in Gram-negative bacteria.
CC {ECO:0000256|HAMAP-Rule:MF_00057}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3-deoxy-alpha-D-manno-oct-2-ulosonate + CTP = CMP-3-deoxy-
CC beta-D-manno-octulosonate + diphosphate; Xref=Rhea:RHEA:23448,
CC ChEBI:CHEBI:33019, ChEBI:CHEBI:37563, ChEBI:CHEBI:85986,
CC ChEBI:CHEBI:85987; EC=2.7.7.38; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_00057};
CC -!- PATHWAY: Nucleotide-sugar biosynthesis; CMP-3-deoxy-D-manno-
CC octulosonate biosynthesis; CMP-3-deoxy-D-manno-octulosonate from 3-
CC deoxy-D-manno-octulosonate and CTP: step 1/1. {ECO:0000256|HAMAP-
CC Rule:MF_00057}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00057}.
CC -!- SIMILARITY: Belongs to the KdsB family. {ECO:0000256|HAMAP-
CC Rule:MF_00057}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
