Glossary: CDP-α-D-paratose = CDP-3,6-dideoxy-α-D-glucose = CDP-3,6-dideoxy-α-D-ribo-hexose
Other name(s): rfbS (gene name)
Systematic name: CDP-α-D-paratose:NADP+ 4-oxidoreductase
Comments: 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).
