ENTRY       EC 1.8.99.1
NAME        Sulfite reductase
CLASS       Oxidoreductases
            Acting on a sulfur group of donors
            With other acceptors
SYSNAME     Hydrogen-sulfide:(acceptor) oxidoreductase
REACTION    Hydrogen sulfide + Acceptor + 3 H2O = Sulfite + Reduced acceptor
SUBSTRATE   Hydrogen sulfide
            Acceptor
            H2O
            Methyl viologen
PRODUCT     Sulfite
            Reduced acceptor
COFACTOR    Iron
COMMENT     An iron-protein. A stoichiometry of six molecules of reduced
            methyl viologen per molecule of sulfide formed was found.
PATHWAY     PATH: MAP00450  Selenoamino acid metabolism
