Glucose-1-phosphate cytidylyltransferase
Template:Infobox enzyme In enzymology, a glucose-1-phosphate cytidylyltransferase (Template:EC number) 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.[1][2]
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.[3]
Structural studies
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes Template:PDB link and Template:PDB link.
