Catalase from bovine liver catalyzes the decomposition of H2O2 into water and oxygen.1,2
One unit will decompose 1.0 μmole of H2O2 per min at pH 7.0 at 25 °C, while the H2O2 conc. falls from 10.3 to 9.2 mM, measured by the rate of decrease of A240.
Catalase from bovine liver is a tetramer consisting of four equal subunits with a molecular weight of 60 kDa each. Each subunit contains iron bound to a protoheme IX group. The enzyme also strongly binds NADP, which is in close proximity to the heme group.
