MeSH definition : An enzyme that phosphorylates myosin light chains in the presence of ATP to yield
myosin-light chain phosphate and ADP, and requires calcium and CALMODULIN. The 20-kDa
light chain is phosphorylated more rapidly than any other acceptor, but light chains
from other myosins and myosin itself can act as acceptors. The enzyme plays a central
role in the regulation of smooth muscle contraction.;
