In enzymology, a glucose-1-phosphate cytidylyltransferase (EC 2.7.7.33) is an enzyme that catalyzes the chemical reaction

CTP + alpha-D-glucose 1-phosphate diphosphate + CDP-glucose

Thus, the two substrates of this enzyme are CTP and alpha-D-glucose 1-phosphate, whereas its two products are diphosphate and CDP-glucose.

This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases). The systematic name of this enzyme class is CTP:alpha-D-glucose-1-phosphate cytidylyltransferase. Other names in common use include CDP glucose pyrophosphorylase, cytidine diphosphoglucose pyrophosphorylase, cytidine diphosphate glucose pyrophosphorylase, cytidine diphosphate-D-glucose pyrophosphorylase, and CTP:D-glucose-1-phosphate cytidylyltransferase. This enzyme participates in starch and sucrose metabolism and nucleotide sugars metabolism.

Structural studies

As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 1TZF and 1WVC.
