Effect of Calcium on Synthetic Myosin Minifilamentst Pearl Cheung and Emil Reisler*
ABSTRACT:
The effect of Ca2+on the structural properties of myosin filaments has been examined by employing myosin minifilaments as a model system. Paired sedimentation studies of myosin minifilaments at pH 8.0 reveal only a minor increase in their sedimentation coefficient (0.7 f 0.3%) upon binding of Ca2+ (pCa = 4.5). This increase and the larger change observed at pH 7.0 (
