Molecular Morphology of Myosin

Abstract

RECENT investigations of the Szent-Györgyi school1 have led to much new information about myosin and its role in muscular contraction. One of the main results is that myosin can be extracted from muscle in two forms: myosin s.str. and actomyosin. From both proteins threads can be drawn; those of actomyosin show a considerable contraction upon addition of adenosinetriphosphate. In solution, both forms are distinguished by the much higher viscosity of actomyosin.
