An iron protein. The enzyme participates in sulfate assimilation. While it is usually found in cyanobacteria, plants and algae, it has also been reported in bacteria . Different from EC 1.8.99.5, dissimilatory sulfite reductase, which is involved in prokaryotic sulfur-based energy metabolism. cf. EC 1.8.1.2, assimilatory sulfite reductase (NADPH).

The expected taxonomic range for this enzyme is: Bacteria, Eukaryota, Archaea

Synonyms
cmsirb, zmsir, ferredoxin-dependent sulfite reductase, ferredoxin-sulfite reductase, ferredoxin sulfite reductase, pssir, dcp68, cmg021c, fdsir, ferredoxin and sulfite reductase, more
