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.
