crystal structure at 2 A resolution and comparison with that of the phylogenetically related assimilatory sulfite reductase aSir. Dissimilatory sulfite reductase dSir is organized as a heterotetrameric complex composed of two catalytically independent alphabeta heterodimers. aSir is a monomeric protein built of two fused modules. aSir binds one siroheme-[4Fe-4S] center, dSir harbors two of them within each alphabeta heterodimer. Only one siroheme-[4Fe-4S] center in each alphabeta heterodimer is catalytically active, whereas access to the second one is blocked by a tryptophan residue | Archaeoglobus fulgidus |
