(myosin-light-chain) phosphatase

In enzymology, a [myosin-light-chain] phosphatase is an enzyme that catalyzes the chemical reaction


 * [myosin light-chain] phosphate + H2O $$\rightleftharpoons$$ [myosin light-chain] + phosphate

Thus, the two substrates of this enzyme are myosin light-chain phosphate and H2O, whereas its two products are [myosin light-chain] and phosphate.

This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name of this enzyme class is [myosin-light-chain]-phosphate phosphohydrolase. Other names in common use include myosin light chain kinase phosphatase, myosin phosphatase, myosin phosphatase, protein phosphatase 2A, and myosin-light-chain-phosphatase.

Structural studies
As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code.
