Enzyme Information
| 1.8.7.1 |
Assimilatory sulfite reductase (ferredoxin).
based on mapping to UniProt P9WJ03
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.
