ENTRY       EC 1.11.1.6
NAME        Catalase
CLASS       Oxidoreductases
            Acting on a peroxide as acceptor
SYSNAME     Hydorogen-peroxide:hydrogen-peroxide oxidoreductase
REACTION    2 H2O2 = O2 + 2 H2O
SUBSTRATE   H2O2
            Ethanol
PRODUCT     O2
            H2O
COFACTOR    Heme
            Manganese
COMMENT     A hemoprotein. Several organic substances, especially ethanol,
            can act as hydrogen donor. A manganese protein containing Mn(III)
            in the resting state, which also belongs here, is often called
            pseudocatalase.
