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. {ECO:0000255|HAMAP-
CC Rule:MF_01541}.
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 Rule:MF_01541};
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01541};
CC Note=Binds 1 FAD per subunit. {ECO:0000255|HAMAP-Rule:MF_01541};
CC -!- COFACTOR:
CC Name=FMN; Xref=ChEBI:CHEBI:58210;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01541};
CC Note=Binds 1 FMN per subunit. {ECO:0000255|HAMAP-Rule:MF_01541};
CC -!- PATHWAY: Sulfur metabolism; hydrogen sulfide biosynthesis; hydrogen
CC sulfide from sulfite (NADPH route): step 1/1. {ECO:0000255|HAMAP-
CC Rule:MF_01541}.
CC -!- SUBUNIT: Alpha(8)-beta(8). The alpha component is a flavoprotein, the
CC beta component is a hemoprotein. {ECO:0000255|HAMAP-Rule:MF_01541}.
CC -!- SIMILARITY: Belongs to the NADPH-dependent sulphite reductase
CC flavoprotein subunit CysJ family. {ECO:0000255|HAMAP-Rule:MF_01541}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the flavodoxin
CC family. {ECO:0000255|HAMAP-Rule:MF_01541}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the flavoprotein
CC pyridine nucleotide cytochrome reductase family. {ECO:0000255|HAMAP-
CC Rule:MF_01541}.
