Abstract
Mitochondrial respiration can be inhibited in vitro by a complex of exotoxins elaborated by Staphylococcus aureus. This complex, designated Succinic Oxidase Factor, consists of two components, one of which (A) has a molecular weight of 75,000, is heat-stable, and interferes with cytochrome c oxidase and the other (B) has a molecular weight of 42,000, is heat-labile, and interferes with succinate-cytochrome c reductase. Each component can be separated by Sephadex G200 chromatography and purified by isoelectric focussing. Component A focussed at pH 3.4 and component B focussed at pH 4.5. Antibody prepared in rabbits to Succinic Oxidase Factor could neutralise the biological activities of each component separately or the whole complex and could react serologically with each component in an agar precipitation test.
