Hamed RR, Maharem TM, Abdel Fatah M, Ataya FS (1998) Purification of peroxidase isoenzymes from turnip roots. Phytochem. 48, 1291-1294 ISSN: 0031-9422 (Impact factor 3.3), http://dx.doi.org/10.1016/S0031-9422(97)00852-2,

Simple reproducible procedures for purification of the main soluble (S) and ionically bound (IB) cationic peroxidase isoenzymes from turnip roots were established. The procedures included ammonium sulfate precipitation of the isoenzymes, chromatographic separation of the main isoenzymes using cellulose phosphate columns and purification to homogeneity by hydrophobic interaction chromatography on phenyl Sepharose columns. The specific activity of the phenyl Sepharose purified S and IB isoenzymes were 2760 and 896 units/mg protein with 140 and 4.8 fold increase over the crude extract and 38 and 13% recovery. The pH maxima and K(m) for phenol and H2O2 of purified S and IB were determined.
