Hence, this enzyme has one substrate, CDP-3,6-dideoxy-D-glucose, and one product, CDP-3,6-dideoxy-D-mannose.
This enzyme belongs to the family of isomerases, specifically those racemases and epimerases acting on carbohydrates and derivatives. The systematic name of this enzyme class is CDP-3,6-dideoxy-D-glucose 2-epimerase. Other names in common use include CDP-paratose epimerase, cytidine diphosphoabequose epimerase, cytidine diphosphodideoxyglucose epimerase, cytidine diphosphoparatose epimerase, and cytidine diphosphate paratose-2-epimerase. It is also incorrectly known as CDP-abequose epimerase, and CDP-D-abequose 2-epimerase. This enzyme participates in starch and sucrose metabolism. It employs one cofactor, NAD+.
