In enzymology a low-density-lipoprotein receptor kinase (EC 2.7.11.29) is an enzyme that catalyzes the chemical reactionATP + [low-density-lipoprotein receptor]-L-serine ADP + [low-density-lipoprotein receptor]-O-phospho-L-serineThus the two substrates of this enzyme are ATP and [[[low-density-lipoprotein receptor]-L-serine]] whereas its two products are ADP and [[[low-density-lipoprotein receptor]-O-phospho-L-serine]].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).
