Einsteinium 168-170 thiosulfate sulfurtransferase Bos taurus 44-53 11131146-5 2000 We have studied the unfolding and refolding of three rhodanese forms whose crystal structures are known: ES, containing the transferred sulfur as a persulfide; E, without the transferred sulfur, and carboxymethylated rhodanese (CMR), in which the active site was blocked by chemical modification. Einsteinium 105-107 thiosulfate sulfurtransferase Bos taurus 53-62 3466649-8 1987 The substrate, thiosulfate, could reactivate the enzyme up to 70% in 1 h with ES as compared to 24 h with E. Tetrathionate modification of rhodanese could be correlated with the changes in intrinsic fluorescence and with the binding of the active site reporter 2-anilinonaphthalene-8-sulfonic acid (2,8-ANS). Einsteinium 78-80 thiosulfate sulfurtransferase Bos taurus 139-148 6948580-3 1982 The effect with ES is fully reversible and almost completely so with E. Fluorescence depolarization sudies with thiosulfate sulfurtransferase labeled at a number of different sites with the fluorosphore dimethylaminonaphthalene show a sharp increase in the polarization starting at 27 degrees C when the temperature/viscosity ratio is varied with temperature and no transition when the ratio is varied with glycerol.
