Reaction: [myosin light-chain] phosphate + H2O = [myosin light-chain] + phosphate
Other name(s): myosin light chain kinase phosphatase; myosin phosphatase; myosin phosphatase; protein phosphatase 2A; myosin-light-chain-phosphatase
Systematic name: [myosin-light-chain]-phosphate phosphohydrolase
Comments: The enzyme is composed of three subunits. The holoenzyme dephosphorylates myosin light chains and EC 2.7.11.18, myosin-light-chain kinase, but not myosin; the catalytic subunit acts on all three substrates.
