In enzymology a dephospho-[reductase kinase] kinase (EC 2.7.11.3) is an enzyme that catalyzes the chemical reactionATP + dephospho-[hydroxymethylglutaryl-CoA reductase (NADPH)] kinase ADP + [hydroxymethylglutaryl-CoA reductase (NADPH)] kinaseThus the two substrates of this enzyme are ATP and [[dephospho-[hydroxymethylglutaryl-CoA reductase (NADPH)] kinase]] whereas its two products are ADP and [[[hydroxymethylglutaryl-CoA reductase (NADPH)] kinase]].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).
