A molecular subunit of beef hepatocatalase that exhibits high enzymatic activity as a peroxidase-oxidase and is essentially free of catalatic action has been isolated. The hepatocatalase peroxidase subunit (HCP) is a depolymerization product of hepatocatalase with an estimated molecular weight of 80,000 ± 12,000. It was obtained in the form of a stable, lyophilized, water-soluble powder by a procedure involving alkaline hydrolysis, dialysis, and lyophilization. Like hepatocatalase, HCP is also a porphyrin enzyme. The availability of this preparation has made it possible to study the peroxidatic function of catalase without interference from its catalatic action and to obtain some basic
