KEGG ENZYME: 1.8.2.1

ENZYME: 1.8.2.1

Entry

EC 1.8.2.1                  Enzyme

Name

sulfite dehydrogenase (cytochrome);
sulfite cytochrome c reductase;
sulfite-cytochrome c oxidoreductase;
sulfite oxidase (ambiguous);
sulfite dehydrogenase (ambiguous);
sorAB (gene names)

Class

Oxidoreductases;
Acting on a sulfur group of donors;
With a cytochrome as acceptor

Sysname

sulfite:ferricytochrome-c oxidoreductase

Reaction(IUBMB)

sulfite + 2 ferricytochrome c + H2O = sulfate + 2 ferrocytochrome c + 2 H+ [RN:R00528]

Reaction(KEGG)

R00528

Substrate

sulfite [CPD:C00094];
ferricytochrome c [CPD:C00125];
H2O [CPD:C00001]

Product

sulfate [CPD:C00059];
ferrocytochrome c [CPD:C00126];
H+ [CPD:C00080]

Comment

Associated with cytochrome c-551. The enzyme from the bacterium Starkeya novella contains a molybdopyranopterin cofactor and a smaller monoheme cytochrome c subunit. cf. EC 1.8.5.6, sulfite dehydrogenase (quinone).
