Biocatalytic oxidation of phenolic compounds by bovine methemoglobin in the presence of H2O2: Quantitative structure-activity relationships

► The kinetics of metHb-catalyzed oxidation of a group of phenols were analyzed. ► Unusual kinetic behaviour was observed for the phenols here tested. ► QSAR equations for a number of physicochemical parameters were established. ► A relationship between the peroxidase and catalase activities of metHb was found. ► Bovine metHb might represent a good economical alternative to other peroxidases.
