ID   3.1.3.53
DE   [myosin-light-chain] phosphatase.
AN   myosin light-chain kinase phosphatase.
AN   myosin phosphatase.
CA   (1) H2O + O-phospho-L-seryl-[myosin light chain] = L-seryl-[myosin light
CA   chain] + phosphate.
CA   (2) H2O + O-phospho-L-threonyl-[myosin light chain] = L-threonyl-[myosin
CA   light chain] + phosphate.
CC   -!- Composed of three subunits.
CC   -!- The holoenzyme dephosphorylates myosin light chains and EC 2.7.11.31,
CC       but not myosin; the catalytic subunit acts on all three substrates.
