Superoxide dismutase in strains of the genus Flavobacterium: isolation and characterization.
Two electrophoretically different forms of superoxide dismutase, one of them containing manganese-protein and the other iron-protein, were detected in eleven different strains of the genus Flavobacterium. The activities of the different strains were similar to those described for other bacteria. The two molecular forms of the enzyme differed clearly with regard to activity, electrophoretic behaviour, sensitivity to cyanide and peroxide, and NaCl requirement. Both molecular forms were isolated from Flavobacterium halmephilum. Molecular mass absorption spectra, metal content, optimum pH, heat-sensitivity and stability were described.
