Tropomyosin kinase

Tropomyosin kinase

In enzymology, a tropomyosin kinase (EC number|2.7.11.28) is an enzyme that catalyzes the chemical reaction

:ATP + tropomyosin ightleftharpoons ADP + O-phosphotropomyosin

Thus, the two substrates of this enzyme are ATP and tropomyosin, whereas its two products are ADP and O-phosphotropomyosin.

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:tropomyosin O-phosphotransferase. Other names in common use include tropomyosin kinase (phosphorylating), and STK.
