Myosin-light-chain phosphatase
CLASS OF ENZYMES
Myosin light-chain phosphatase; Myosin light chain phosphatase; MLCP; EC 3.1.3.53; (myosin-light-chain) phosphatase; (myosin-light-chain)-phosphate phosphohydrolase
Myosin light-chain phosphatase, more commonly called myosin phosphatase (), is an enzyme (specifically a serine/threonine-specific protein phosphatase) that dephosphorylates the regulatory light chain of myosin II. This dephosphorylation reaction occurs in smooth muscle tissue and initiates the relaxation process of the muscle cells.
