ATP + H2O + myosin bound to actin filament at position n = ADP + phosphate + myosin bound to actin filament at position n+1
Substrate
ATP [CPD:C00002];
H2O [CPD:C00001];
myosin bound to actin filament at position n
Product
ADP [CPD:C00008];
phosphate [CPD:C00009];
myosin bound to actin filament at position n+1
Comment
Proteins of the contractile apparatus of muscle and nonmuscle cells; myosin molecule consists of two heavy chains (about 200 kDa) and two pairs of light chains (15--27 kDa). The head region of the heavy chain contains actin- and ATP-binding sites. ATP hydrolysis provides energy for actomyosin contraction.
