Inactivation of 3 alpha-hydroxysteroid dehydrogenase by superoxide radicals. Modification of histidine and cysteine residues causes the conformational change.

3 alpha-Hydroxysteroid dehydrogenase (EC 1.1.1.50) from Pseudomonas testosterone was inactivated by superoxide radicals generated by the aerobic xanthine oxidase reaction. Superoxide dismutase, NAD+, bovine serum albumin and histidine and cysteine as free amino acids partially protected the enzyme f...
