Myosin-light-chain phosphatase         
  • A 3D representation of PP1 (shown in red) and a portion of MYPT1 (shown in blue), with the manganese ion catalysts shown in white.  The yellow lines mark the grooves that are critical for enzyme binding and catalysis.
  • doi-access= free}}</ref>  The substrates and products are bold and in red, and the manganese ions are in blue.  The alcohol group shown on myosin after dephosphorylation is the alcohol on Ser-19.
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.

Myosin
Myosins (}} }}) are a superfamily of motor proteins best known for their roles in muscle contraction and in a wide range of other motility processes in eukaryotes. They are ATP-dependent and responsible for actin-based motility.
