Modulation of Rigor and Myosin ATPase Activity in Rat Cardiomyocytes

Ischaemic myocardium undergoes calcium-independent contracture at millimolar tissue ATP, though in actomyosin solutions ATP must be reduced to micromolar before rigor complexes form. This contracture is associated with myosin ATPase activity that may contribute to tissue de-energization. Here we use...
