title: [Effect of Ca2+ on the motility of myosin head in the F-actin-HMM complex].
abstract: Using polarization microfluorimetry, the effect of Ca2+ on the mode of interaction between heavy meromyosin labeled with 1.5-IAEDANS and F-actin was studied. The results obtained suggest that both the orientation and motility of myosin heads in the F-actin-heavy meromyosin complex depend on Ca2+ concentration. The experimental results are suggestive of the existence of a myosin-coupled regulatory system in skeletal muscles.
