In enzymology, a<unk> -polymerase-subunit<unk>  (EC 2.7.11.23) is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are ATP and  [DNA-directed<unk>  polymerase], whereas its two products are ADP and phospho- [DNA-directed<unk>  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<unk> s).  The systematic name of this enzyme class is ATP:[DNA-directed<unk>  polymerase] phosphotransferase. Other names in common use include CTD<unk> , and STK9.
