ENTRY       EC 1.9.3.2
NAME        Pseudomonas cytochrome oxidase
            Cytochrome cd
CLASS       Oxidoreductases
            Acting on heme group of donors
            With oxygen as acceptor
SYSNAME     Ferrocytochrome-c:oxygen oxidoreductase
REACTION    4 Ferrocytochrome c2 + O2 = 4 Ferricytochrome c2 + 2 H2O;
            2 Ferrocytochrome c2 + Nitrite = 2 Ferricytochrome c2 + H2O +
            Nitric oxide
SUBSTRATE   Ferrocytochrome c2
            O2
            Nitrite
            Hydroxylamine
PRODUCT     Ferricytochrome c2
            H2O
            Nitric oxide
            NH3
COMMENT     Hemeprotein contains cytochrome c and d. Nitrite and hydroxylamine 
            can act as acceptors.
