we next prepared cell-free extracts of k12 , rm312 , and rm1385 and tested the activity of their soluble proteases against proteins ( albumin , hemoglobin , superoxide dismutase , catalase ) which had been oxidatively denatured ( in vitro ) by exposure to .oh , .oh + o2- ( +o2 ) , h2o2 , or ascorbate plus iron .
