Accepted name: 3-deoxy-α-D-manno-octulosonate 8-oxidase
Reaction: 3-deoxy-α-D-manno-octulopyranosonate + O2 = 3,8-dideoxy-8-oxo-α-D-manno-octulosonate + H2O2
Glossary: 3-deoxy-α-D-manno-octulosonate = Kdo
3,8-dideoxy-8-oxo-α-D-manno-octulosonate = (2R,4R,5R,6S)-2,4,5-trihydroxy-6-[(1S)-1-hydroxy-2-oxoethyl]oxane-2-carboxylate
Other name(s): kdnB (gene name)
Systematic name: 3-deoxy-α-D-manno-octulopyranosonate:oxygen 8-oxidoreductase
Comments: The enzyme, characterized from the bacterium Shewanella oneidensis, is involved in the formation of 8-amino-3,8-dideoxy-α-D-manno-octulosonate, an aminated form of Kdo found in lipopolysaccharides of members of the Shewanella genus. cf. EC, 8-amino-3,8-dideoxy-α-D-manno-octulosonate transaminase.
