Reaction(IUBMB)
CDP-alpha-D-paratose + NADP+ = CDP-4-dehydro-3,6-dideoxy-alpha-D-glucose + NADPH + H+ [RN:
R04265 ]
Reaction(KEGG)
Substrate
Product
CDP-4-dehydro-3,6-dideoxy-alpha-D-glucose [CPD:
C04297 ];
NADPH [CPD:
C00005 ];
H+ [CPD:
C00080 ]
Comment
The enzyme is involved in synthesis of paratose and tyvelose, unusual 3,6-dideoxyhexose sugars that form part of the O-antigen in the lipopolysaccharides of several enteric bacteria. Isolated from Salmonella enterica subsp. enterica serovar Typhi (Salmonella typhi).
