Protein attributes
| Sequence length | 595 AA. |
| Sequence status | Complete. |
| Protein existence | Inferred from homology |
General annotation (Comments)
| Function | Component of the sulfite reductase complex that catalyzes the 6-electron reduction of sulfite to sulfide. This is one of several activities required for the biosynthesis of L-cysteine from sulfate. The flavoprotein component catalyzes the electron flow from NADPH -> FAD -> FMN to the hemoprotein component By similarity. HAMAP MF_01541 |
| Catalytic activity | H2S + 3 NADP+ + 3 H2O = sulfite + 3 NADPH. HAMAP MF_01541 |
| Cofactor | Binds 1 FAD per subunit By similarity. HAMAP MF_01541 Binds 1 FMN per subunit By similarity. HAMAP MF_01541 |
| Pathway | Sulfur metabolism; hydrogen sulfide biosynthesis; hydrogen sulfide from sulfite (NADPH route): step 1/1. HAMAP MF_01541 |
| Subunit structure | Alpha(8)-beta8. The alpha component is a flavoprotein, the beta component is a hemoprotein By similarity. |
| Sequence similarities | Contains 1 FAD-binding FR-type domain. Contains 1 flavodoxin-like domain. |
