Liberation of bromine or iodine in presence KBr or KI and H2O2 by the enzyme
The experiment was performed following the method described previously in which liberated halogens from trihalide complex with halogen ions which can be monitored spectrophotometrically. The absorption spectra of tribromide and triiodide formed in the reaction mixture 1 ml consisting of 20 mM KBr or KI, 0.1 mM H2O2 and suitable amount of the enzyme in 20 mM sodium succinate acid buffer pH3 at 30 c were recorded using the UV VIS spectrophotometer as mentioned in the enzyme assay section.
