Sulfide-cytochrome-c reductase (flavocytochrome c) (EC 1.8.2.3) is an enzyme with systematic name hydrogen-sulfide:flavocytochrome c oxidoreductase.^{[1][2][3][4][5][6]} This enzyme catalyses the following chemical reaction

hydrogen sulfide + 2 ferricytochrome c $\rightleftharpoons$ sulfur + 2 ferrocytochrome c + 2 H⁺

The enzyme from Allochromatium vinosum contains covalently bound FAD and c-type hemes.
