A voltammetric study of interdomain electron transfer within sulfite oxidase.

Abstract:

Protein film voltammetry of chicken liver sulfite oxidase (SO) bound at the pyrolytic graphite "edge" or modified gold electrodes shows that catalytic electron transport is controlled by the inherent electrochemical characteristics of the heme b domain and conformational changes that allow intramolecular electron transfer with the molybdenum active site. In the absence of sulfite, a single nonturnover electrochemical signal is observed at +90 mV (vs SHE) that is assigned to heme b. In the pre...
