Abstract excerpt
A rapid spectrophotometric assay to determine the activities of HPI and HPII catalases in Escherichia coli extracts has been developed. This assay is based upon the differential heat stabilities of the two enzymes and offers significant advantages over previous methods for quantitation of their a...
