Abstract
The isolation and purification of bromoperoxidases from 3 marine subtropical green algae is described. In the presence of KBr and H2O2, each halide-specific enzyme catalyzes the bromination of monochlorodimedone (2-chloro-5,5-dimethylcyclohexane-1,3-dione) to bromochlorodimedone (2-bromo-2-chloro-5,5-dimethylcyclohexane-1,3-dione). The enzymes also catalyze the oxidation of pyrogallol, O-phenylenediamine and I- to I3-. Preliminary characterization of these enzymes reveals acidic pH optima, high thermal stability, sensitivity to higher H2O2 concentrations and apparent MW ranging 48,000-60,000.This publication has 13 references indexed in Scilit:
