the effect of positive and negative stress on myosin cross-bridge orientation in glycerinated muscle fibers was investigated by using fluorescence polarization spectroscopy of the emission from the covalent label tetramethyl-rhodamine-5- ( and -6 ) -iodoacetamide ( iatr ) specifically modifying sulfhydryl one ( sh1 ) on the myosin heavy chain .
