1 GO annotations of cellular component

Name Definition
sulfite reductase complex (NADPH) A multisubunit iron flavoprotein, which in yeast is composed of 2 alpha and 2 beta subunits. Catalyzes the reduction of sulfite to sulfide.

5 GO annotations of molecular function

Name Definition
4 iron, 4 sulfur cluster binding Binding to a 4 iron, 4 sulfur (4Fe-4S) cluster; this cluster consists of four iron atoms, with the inorganic sulfur atoms found between the irons and acting as bridging ligands.
heme binding Binding to a heme, a compound composed of iron complexed in a porphyrin (tetrapyrrole) ring.
metal ion binding Binding to a metal ion.
NADP binding Binding to nicotinamide-adenine dinucleotide phosphate, a coenzyme involved in many redox and biosynthetic reactions; binding may be to either the oxidized form, NADP+, or the reduced form, NADPH.
sulfite reductase (NADPH) activity Catalysis of the reaction: hydrogen sulfide + 3 NADP+ + 3 H2O = sulfite + 3 NADPH + 3 H+.

3 GO annotations of biological process

Name Definition
cysteine biosynthetic process The chemical reactions and pathways resulting in the formation of cysteine, 2-amino-3-mercaptopropanoic acid.
hydrogen sulfide biosynthetic process The chemical reactions and pathways resulting in the formation of hydrogen sulfide, H2S.
sulfate assimilation The pathways by which inorganic sulfate is processed and incorporated into sulfated compounds.
