1.15.1.2 additional information
-
 additional information enzyme redox potentials, and stopped-flow kinetics of the reduction of superoxide reductase-Zn(II)-Fe(III) and superoxide reductase-Fe(III)-Fe(III), overview. Smaller reaction rate constants are observed for the superoxide reductase-Fe(III)-Fe(III) and oxidized superoxide reductase-Zn(II)-Fe(III) forms, in both cases centre II has to be reduced prior to the reaction with superoxide radical, leading to a slower initial reaction rate Desulfovibrio vulgaris
