Abstract
The oxidation of benzoin by (NEt(4))(2)[M(VI)O(2)(S2C6H4)(2)] (M = W ( 1) and Mo (2)) (S2C6H4 = 1,2-benzenedithiolate) was studied to clarify the role of tungsten ions in hyperthermostable enzymes. The reaction was analyzed by saturation kinetics, primary isotope effects of k(H)/k (D), and the high temperture reaction at 100 degrees C. The rate const ants were also compared with those of the selenolato analogs.
