CC   -!- FUNCTION: Component of the sulfite reductase complex that
CC       catalyzes the 6-electron reduction of sulfite to sulfide. This is
CC       one of several activities required for the biosynthesis of L-
CC       cysteine from sulfate. The flavoprotein component catalyzes the
CC       electron flow from NADPH -> FAD -> FMN to the hemoprotein
CC       component. {ECO:0000256|SAAS:SAAS00064038}.
CC   -!- CATALYTIC ACTIVITY: H(2)S + 3 NADP(+) + 3 H(2)O = sulfite + 3
CC       NADPH. {ECO:0000256|SAAS:SAAS00064025}.
CC   -!- COFACTOR:
CC       Note=Binds 1 FAD per subunit. {ECO:0000256|PIRSR:PIRSR000207-1,
CC       ECO:0000256|SAAS:SAAS00064043};
CC   -!- COFACTOR:
CC       Note=Binds 1 FMN per subunit. {ECO:0000256|PIRSR:PIRSR000207-1,
CC       ECO:0000256|SAAS:SAAS00064057};
CC   -!- PATHWAY: Sulfur metabolism; hydrogen sulfide biosynthesis;
CC       hydrogen sulfide from sulfite (NADPH route): step 1/1.
CC       {ECO:0000256|SAAS:SAAS00064032}.
CC   -!- SUBUNIT: Alpha(8)-beta(8). The alpha component is a flavoprotein,
CC       the beta component is a hemoprotein.
CC       {ECO:0000256|SAAS:SAAS00064046}.
CC   -!- SIMILARITY: Contains FAD-binding FR-type domain.
CC       {ECO:0000256|SAAS:SAAS00064050}.
CC   -!- SIMILARITY: Contains flavodoxin-like domain.
CC       {ECO:0000256|SAAS:SAAS00064022}.
