IntEnz Enzyme Nomenclature
EC 1.8.7.1

Names

Accepted name:
assimilatory sulfite reductase (ferredoxin)
Other names:
ferredoxin-sulfite reductase
SIR (gene name)
sulfite reductase (ferredoxin)
Systematic name:
hydrogen-sulfide:ferredoxin oxidoreductase

Reaction

Cofactor

Comments:

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 [4]. cf. EC 1.8.1.2, assimilatory sulfite reductase (NADPH).
