Accepted name: CDP-paratose 2-epimerase

Reaction: CDP-α-D-paratose = CDP-α-D-tyvelose

Glossary: CDP-α-D-tyvelose = CDP-3,6-dideoxy-α-D-mannose = CDP-3,6-dideoxy-α-D-arabino-hexose
CDP-α-D-paratose = CDP-3,6-dideoxy-α-D-glucose = CDP-3,6-dideoxy-α-D-ribo-hexose

Other name(s): CDP-paratose epimerase; cytidine diphosphoabequose epimerase; cytidine diphosphodideoxyglucose epimerase; cytidine diphosphoparatose epimerase; cytidine diphosphate paratose-2-epimerase; CDP-abequose epimerase (incorrect); CDP-D-abequose 2-epimerase (incorrect)

Systematic name: CDP-3,6-dideoxy-D-glucose 2-epimerase

Comments: Requires NAD+. CDP-paratose (CDP-3,6-dideoxy-D-glucose), is more systematically called CDP-α-3,6-dideoxy-D-ribo-hexose. CDP-tyvelose (CDP-3,6-dideoxy-D-mannose) is systematically called CDP-3,6-dideoxy-D-arabino-hexose.
