Abstract

Previous investigations have demonstrated the presence of both superoxide dismutase and catalase enzymes in several intracellular pathogens, including a number of mycobacterial species. These enzymes are believed to be involved in the protection of the pathogen from the bactericidal products of oxidative metabolism. Superoxide dismutase and catalase were identified in crude extracts of by polyacrylamide gel electrophoresis. Inhibition experiments showed that the superoxide dismutase probably contained manganese as the metal cofactor. Other mycobacterial species examined for comparison produced bands of superoxide dismutase activity with a different mobility to that of , suggesting possible structural differences between the enzymes.
