Sulfite reductase (ferredoxin) explained

Sulfite reductase (ferredoxin)
Ec Number:	1.8.7.1
Cas Number:	37256-50-1

Sulfite reductase (ferredoxin) (ferredoxin-sulfite reductase) is an enzyme with systematic name hydrogen-sulfide:ferredoxin oxidoreductase.^[1] This enzyme catalises the following chemical reaction

hydrogen sulfide + 6 oxidized ferredoxin + 3 H₂O

\rightleftharpoons sulfite + 6 reduced ferredoxin + 6 H⁺

This sulfite reductase is an iron protein.
