From: Copper(II) ions affect the gating dynamics of the 20S proteasome: a molecular and in cell study
(A) Typical deconvolution of normalized tryptophan fluorescence spectra of the 20S proteasome at pH 7.6 recorded immediately after the addition of 0.018% SDS (normalized experimental spectra – black points; fitting curve - solid line; spectral components – dotted lines). (B) Plot of the wavelength shift of the first spectral component vs time (closed squares). The two dotted lines represent the linear fits of the values obtained before (t < 150 min) and after (t > 150 min) the addition of Cu(II) ions.
