Uridine kinase

Template:Short description Template:Infobox enzyme In enzymology, an uridine kinase (Template:EC number) is an enzyme that catalyzes the chemical reaction

ATP + uridine $\rightleftharpoons$ ADP + UMP

Thus, the two substrates of this enzyme are ATP and uridine, whereas its two products are ADP and UMP.

This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:uridine 5'-phosphotransferase. Other names in common use include pyrimidine ribonucleoside kinase, uridine-cytidine kinase, uridine kinase (phosphorylating), and uridine phosphokinase. This enzyme participates in pyrimidine metabolism.

Structural studies

As of late 2007, 8 structures have been solved for this class of enzymes, with PDB accession codes Template:PDB link, Template:PDB link, Template:PDB link, Template:PDB link, Template:PDB link, Template:PDB link, Template:PDB link, and Template:PDB link.
