Abstract:
Staphylococcus simulans biovar staphylolyticus contains five plasmids designated pACK1 through pACK5. Non-denaturing electrophoretic analysis of an extract prepared from wild-type cells revealed three bands of catalase activity, whereas an extract of cells cured of pACK1 produced only two catalase bands. Cloning and Southern hybridization analysis showed that there is a catalase structural gene on pACK1. The plasmid-specified catalase was the major activity produced under both aerobic and anaerobic conditions of growth.
