CC -!- FUNCTION: Component of the sulfite reductase complex that catalyzes the
CC 6-electron reduction of sulfite to sulfide. This is one of several
CC activities required for the biosynthesis of L-cysteine from sulfate.
CC The flavoprotein component catalyzes the electron flow from NADPH ->
CC FAD -> FMN to the hemoprotein component.
CC {ECO:0000256|PIRNR:PIRNR000207}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3 H2O + hydrogen sulfide + 3 NADP(+) = 4 H(+) + 3 NADPH +
CC sulfite; Xref=Rhea:RHEA:13801, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,

CC Note=Binds 1 FAD per subunit. {ECO:0000256|PIRNR:PIRNR000207,
CC ECO:0000256|PIRSR:PIRSR000207-1};
CC -!- COFACTOR:

CC Evidence={ECO:0000256|PIRNR:PIRNR000207,
CC ECO:0000256|PIRSR:PIRSR000207-1};
CC Note=Binds 1 FMN per subunit. {ECO:0000256|PIRNR:PIRNR000207,
CC ECO:0000256|PIRSR:PIRSR000207-1};
CC -!- PATHWAY: Sulfur metabolism; hydrogen sulfide biosynthesis; hydrogen
CC sulfide from sulfite (NADPH route): step 1/1.
CC {ECO:0000256|PIRNR:PIRNR000207}.
CC -!- SUBUNIT: Alpha(8)-beta(8). The alpha component is a flavoprotein, the
CC beta component is a hemoprotein. {ECO:0000256|PIRNR:PIRNR000207}.
