An investigation of the influence of propyl gallate on the reaction of ATP-ase with myosin and with actomyosin demonstrated that inorganic phosphate evolution declined with increasing propyl gallate concentration. Evidence indicates, however, that propyl gallate is a nonspecific inhibitor. When diphenyl picryl hydrazyl is added to the system ATP-actinomyosin, its concentration is reduced in a manner which suggests the formation of free radicals during ATP hydrolysis.
