(RNA-polymerase)-subunit kinase

(RNA-polymerase)-subunit kinase

In enzymology, a [RNA-polymerase] -subunit kinase (EC number|2.7.11.23) is an enzyme that catalyzes the chemical reaction

:ATP + [DNA-directed RNA polymerase] ightleftharpoons ADP + phospho- [DNA-directed RNA polymerase]

Thus, the two substrates of this enzyme are ATP and [DNA-directed RNA polymerase] , whereas its two products are ADP and [phospho- [DNA-directed RNA polymerase] .

This enzyme belongs to the family of transferases, specifically those transferring a phosphate group to the sidechain oxygen atom of serine or threonine residues in proteins (protein-serine/threonine kinases). The systematic name of this enzyme class is ATP: [DNA-directed RNA polymerase] phosphotransferase. Other names in common use include CTD kinase, and STK9.
