We have measured the microsecond rotational motions of myosin heads in contracting rabbit psoas muscle fibers by detecting the transient phosphorescence anisotropy of eosin-5-maleimide attached specifically to the myosin head. Experiments were performed on small bundles (10-20 fibers) of glycerinated rabbit psoas muscle fibers at 4 degrees C. The isometric(More)
We have developed a method using fluorescence energy transfer (FET) to analyze protein oligomeric structure. Two populations of a protein are labeled with fluorescent donor and acceptor, respectively, then mixed at a defined donor/acceptor ratio. A theoretical simulation, assuming random mixing and association among protein subunits in a ring-shaped(More)
