Enzyme Information
| 2.7.11.7 |
[Myosin heavy-chain] kinase.
based on mapping to UniProt P42527
ATP + [myosin heavy-chain] = ADP + [myosin heavy-chain] phosphate.
-!- The enzyme from Dictyostelium sp. (slime molds) brings about phosphorylation of the heavy chains of Dictyostelium myosin, inhibiting the actin-activated ATPase activity of the myosin. -!- One threonine residue in each heavy chain acts as acceptor. -!- While the enzyme from some species is activated by actin, in other cases Ca(2+)/calmodulin are required for activity. -!- Formerly EC 2.7.1.129.
