title: High protein mobility in skinned rabbit muscle fibres observed by 1H NMR spectroscopy.
abstract: 1H NMR spectra of skinned rabbit muscle fibers show a group of relatively sharp resonance lines which presumably originate from highly mobile protein domains. Comparison with the spectrum of myosin subfragment 1 suggests that these signals may come at least partly from mobile regions of the myosin head. NMR could possibly be used to characterize the movements of crossbridges in force generation.
