IntEnz Enzyme Nomenclature


Accepted name:
tropomyosin kinase
Other names:
tropomyosin kinase (phosphorylating)
Systematic name:
ATP:tropomyosin O-phosphotransferase



The enzyme phosphorylates casein equally well, and histone and phosvitin to a lesser extent. The acceptor is a serine residue in the protein.
