myosin light chain kinase

An enzyme in smooth muscle cells that catalyzes the transfer of a phosphate group from adenosine triphosphate to myosin, which initiates contraction.

The muscle contraction pathways regulated by calcium ions show three major mechanisms [11-13]; i) Troponin-tropomyosin complex system which is related to actin-filament in skeletal muscle and cardiac muscle, ii) Myosin light chain kinase mechanism which occurs during muscle contraction with calmodulin in vertebrate's smooth muscles, iii) Calcium ions bind directly to myosin and induce muscle contraction.
