    Alternative name(s):
    CMP-8-amino-3,8-dideoxy-manno-octulosonate synthase
  • Recommended name:
    3-deoxy-manno-octulosonate cytidylyltransferase (EC:2.7.7.38)
    Alternative name(s):
    CMP-2-keto-3-deoxyoctulosonic acid synthase
    Short name:

Gene namei

  • Name:kdsB

Catalytic activityi

  • CTP + 8-amino-3,8-dideoxy-alpha-D-manno-octulosonate = diphosphate + CMP-8-amino-3,8-dideoxy-alpha-D-manno-octulosonate.
  • CTP + 3-deoxy-D-manno-octulosonate = diphosphate + CMP-3-deoxy-D-manno-octulosonate.

Sequence similaritiesi

Functioni

  • Activates KDO8N (a required 8-carbon sugar) for incorporation into bacterial lipopolysaccharide in the Shewanella genus.
  • Activates KDO (a required 8-carbon sugar) for incorporation into bacterial lipopolysaccharide in Gram-negative bacteria.

Pathwayi

  • Pathwayi: CMP-3-deoxy-D-manno-octulosonate biosynthesis

    This protein is involved in step 1 of the subpathway that synthesizes CMP-3-deoxy-D-manno-octulosonate from 3-deoxy-D-manno-octulosonate and CTP. This subpathway is part of the pathway CMP-3-deoxy-D-manno-octulosonate biosynthesis, which is itself part of Nucleotide-sugar biosynthesis.
  • Pathwayi: lipopolysaccharide biosynthesis

    This protein is involved in the pathway lipopolysaccharide biosynthesis, which is part of Bacterial outer membrane biogenesis.
