ENZYME entry: EC 3.1.3.53

Accepted Name
[myosin-light-chain] phosphatase
Alternative Name(s)
myosin light-chain kinase phosphatase
myosin phosphatase
Reaction catalysed
  • H2O + O-phospho-L-seryl-[myosin light chain] <=> L-seryl-[myosin light chain] + phosphate
  • H2O + O-phospho-L-threonyl-[myosin light chain] <=> L-threonyl-[myosin light chain] + phosphate
Comment(s)
  • Composed of three subunits.
  • The holoenzyme dephosphorylates myosin light chains and EC 2.7.11.31, but not myosin; the catalytic subunit acts on all three substrates.
