| Abstract: | Two anodic isoperoxidases (A1 and A2) from tobacco tissue culture W-38 and two cathodic isoperoxidases (C3 and C4) from tobacco suspension culture WR-132 have been separated and characterized. Molecular weights for each of the isoperoxidases have been determined by two different methods. Only C4 contained a carbohydrate component. The substrate specificity and the pH optima for the four enzymes with each of five substrates were determined. |
