Figure 4From: The intrinsic GTPase activity of the Gtr1 protein from Saccharomyces cerevisiaeRepresentative relative tryptophan fluorescence spectra of purified Gtr1 wild-type protein in the GDP (full line) and GTP γS (hatched line) states. Data are representative of two replica experiments. The spectra of each sample were obtained after normalization to the fluorescence level of the Gtr1-GDP complex.Back to article page
