Kinetic analysis of the GSSH:sulfite sulfurtransferase reaction catalyzed by the rhodanese variants. A and C, dependence of the reaction velocity for sulfur transfer on the concentration of GSSH in the presence of 1 mm sulfite for E102D (A) and P285A (C) rhodanese. B and D, dependence of the reaction velocity on sulfite concentration in the presence of 2 mm GSSH for E102D (B) and P285A (D) rhodanese. The reaction conditions are described under “Experimental Procedures,” and the data are representative of three independent experiments.
