Domain Context

CATH Clusters

Superfamily Sulfite Reductase Hemoprotein, domain 1
Functional Family Sulfite reductase [ferredoxin], chloroplastic

Enzyme Information

1.8.7.1
Assimilatory sulfite reductase (ferredoxin).
based on mapping to UniProt O23813
Hydrogen sulfide + 6 oxidized ferredoxin [iron-sulfur] cluster + 3 H(2)O = sulfite + 6 reduced ferredoxin [iron-sulfur] cluster + 6 H(+).
-!- The enzyme participates in sulfate assimilation. -!- While it is usually found in cyanobacteria, plants and algae, it has also been reported in bacteria (cf. EC 1.8.1.2). -!- Formerly EC 1.8.99.1.
