With NAD+ or NADP+ as acceptor
Sysname
CDP-alpha-D-paratose:NADP+ 4-oxidoreductase
Reaction(IUBMB)
CDP-alpha-D-paratose + NADP+ = CDP-4-dehydro-3,6-dideoxy-alpha-D-glucose + NADPH + H+ [RN:R04265]
Reaction(KEGG)
R04265
Substrate
CDP-alpha-D-paratose [CPD:C03598];
NADP+ [CPD:C00006]
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).
