Myosin heavy chain kinase

In enzymology, a myosin-heavy-chain kinase (EC 2.7.11.7) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are ATP and myosin heavy-chain, whereas its two products are ADP and myosin heavy-chain phosphate.

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:[myosin heavy-chain] O-phosphotransferase. Other names in common use include
