EC 2.6.1.109     
Accepted name: 8-amino-3,8-dideoxy-α-D-manno-octulosonate transaminase
Reaction: 8-amino-3,8-dideoxy-α-D-manno-octulosonate + 2-oxoglutarate = 8-dehydro-3-deoxy-α-D-manno-octulosonate + L-glutamate
Glossary: 3-deoxy-α-D-manno-octulosonate = Kdo
8-dehydro-3-deoxy-α-D-manno-octulosonate = (2R,4R,5R,6S)-2,4,5-trihydroxy-6-[(1S)-1-hydroxy-2-oxoethyl]oxane-2-carboxylate
Other name(s): kdnA (gene name)
Systematic name: 8-amino-3,8-dideoxy-α-D-manno-octulosonate:2-oxoglutarate aminotransferase
Comments: The enzyme, characterized from the bacterium Shewanella oneidensis, forms 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 1.1.3.48, 3-deoxy-α-D-manno-octulosonate 8-oxidase.
