ID   5.6.1.8
DE   myosin ATPase.
CA   ATP + H2O + myosin bound to actin filament at position(n) = ADP +
CA   phosphate + myosin bound to actin filament at position(n+1).
CC   -!- Proteins of the contractile apparatus of muscle and nonmuscle cells;
CC       myosin molecule consists of two heavy chains (about 200 kDa) and two
CC       pairs of light chains (15-27 kDa).
CC   -!- The head region of the heavy chain contains actin- and ATP-binding
CC       sites.
CC   -!- ATP hydrolysis provides energy for actomyosin contraction.
CC   -!- Formerly EC 3.6.1.32 and EC 3.6.4.1.
