[Spectroscopic study of myosin from denervated rabbit muscles].
Spectra of tryptophan UV-fluorescence and UV-absorption of myosin isolated 30 days after denervation of white skeletal muscles of rabbit were studied. It has been observed that fluorescence intensity of such myosin in the maximum decreases. This decrease becomes more pronounced after purification of protein from admixtures. It has been shown that after denervation the absorption at 260 nm increases, however, the difference disappears after myosin purification. The data obtained point to a change of myosin structural state after denervation.
