Mycobacteria produce two classes of catalase, designated T and M. Only the T-catalase also has a peroxidase-like function. When a 3,3'-diaminobenzidine (DAB) peroxidase stain was applied to polyacrylamide gel electrophoresis gels, followed by a ferricyanide negative stain for catalase, isoenzymes

Hemoproteins were revealed in polyacrylamide gels in the presence of sodium dodecyl sulfate by staining with different benzidine derivatives. When the protein samples were treated with either beta-mercaptoethanol or dithiothreitol, a significant decrease in peroxidase activity of the proteins possessing
