The enzyme CDP-glucose 4,6-dehydratase (EC 4.2.1.45) catalyzes the chemical reaction
- CDP-glucose CDP-4-dehydro-6-deoxy-D-glucose + H2O
This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. This enzyme participates in starch and sucrose metabolism. It employs one cofactor, NAD+.
Nomenclature
The systematic name of this enzyme class is CDP-glucose 4,6-hydro-lyase (CDP-4-dehydro-6-deoxy-D-glucose-forming). Other names in common use include:
- cytidine diphosphoglucose oxidoreductase, and
- CDP-glucose 4,6-hydro-lyase.
Structural studies
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 1RKX and 1WVG.
