Diversity of Superoxide-Dismutases Among Clinical and Soil Isolates of Streptomyces Species

Abstract.

Comparison of the nature, activity, and cellular localization of superoxide-dismutases (SOD) from soil and clinical isolates of Streptomyces species was investigated to identify possible factors that could account for the pathological role of the strains isolated from human lesions. Results showed that all of the studied strains possessed a cytoplasmic Ni-SOD. This particular SOD, found in isolates from patients, could be a new taxonomic criterion to identify Streptomyces species with greater precision. A second minor SOD, assimilated to an Fe/Zn-SOD, was detected in some strains, but no relationship was established between the presence of this enzyme and the clinical origin of the strains.
