IPR011787 is a Sulphite reductase, ferredoxin dependent.
<p>Sulphite reductase (ferredoxin) is a cyanobacterial and plant monomeric enzyme distantly related to the iron-sulphur hemoprotein of sulphite reductase (NADPH) found in Proteobacteria and Eubacteria that also catalyses the reduction of sulphite to sulphide [[cite:PUB00076661], [cite:PUB00016903]]. Optimal activity of sulfite reductase (SiR) is essential for normal growth in Arabidopsisis [[cite:PUB00076662]].</p>

GO predictions are based solely on the InterPro-to-GO mappings published by EMBL-EBI, which are in turn based on the mapping of predicted domains to the InterPro dataset. The InterPro-to-GO mapping was last updated on , while the GO metadata was last updated on .
| GO term | Namespace | Name | Definition | Relationships |
|---|---|---|---|---|
| Molecular function | Heme binding | Interacting selectively and non-covalently with heme, any compound of iron complexed in a porphyrin (tetrapyrrole) ring. | ||
| Molecular function | Sulfite reductase (ferredoxin) activity | Catalysis of the reaction: hydrogen sulfide + 3 oxidized ferredoxin + 3 H2O = sulfite + 3 reduced ferredoxin. | ||
| Molecular function | 4 iron, 4 sulfur cluster binding | Interacting selectively and non-covalently with 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. |
