'''Crystal Structure of the Ferredoxin from Thauera aromatica'''<br />


==Overview==
==Crystal Structure of the Ferredoxin from Thauera aromatica==
4-Hydroxybenzoyl-CoA reductase (4-HBCR) is a central enzyme in the, metabolism of phenolic compounds in anaerobic bacteria. The enzyme, catalyzes the reductive removal of the phenolic hydroxyl group from, 4-hydroxybenzoyl-CoA, yielding benzoyl-CoA and water. 4-HBCR belongs to, the xanthine oxidase (XO) family of molybdenum enzymes which occur as, heterodimers, (alphabetagamma)(2). 4-HBCR contains two molybdopterins, four [2Fe-2S] and two [4Fe-4S] clusters and two FADs. A low-potential, Allochromatium vinosum-type ferredoxin containing two [4Fe-4S] clusters, serves as an in vivo electron donor for 4-HBCR. In this work, the, oxygen-sensitive proteins 4-HBCR and the ferredoxin (TaFd) from Thauera, aromatica were crystallized under anaerobic conditions. 4-HBCR, crystallized with PEG 4000 and MPD as precipitant diffracted to about 1.6, A resolution and the crystals were highly suitable for X-ray structure, analysis. Crystals of TaFd were obtained with (NH(4))(3)PO(4) as, precipitant and revealed a solvent content of 77%, which is remarkably, high for a small soluble protein. The structure of TaFd was solved at 2.9, A resolution by the molecular-replacement method using the highly related, structure of the ferredoxin (CvFd) from A. vinosum as a model. Structural, changes between the two ferredoxins around the [4Fe-4S] cluster can be, correlated with their different redox potentials.

4-Hydroxybenzoyl-CoA reductase (4-HBCR) is a central enzyme in the metabolism of phenolic compounds in anaerobic bacteria. The enzyme catalyzes the reductive removal of the phenolic hydroxyl group from 4-hydroxybenzoyl-CoA, yielding benzoyl-CoA and water. 4-HBCR belongs to the xanthine oxidase (XO) family of molybdenum enzymes which occur as heterodimers, (alphabetagamma)(2). 4-HBCR contains two molybdopterins, four [2Fe-2S] and two [4Fe-4S] clusters and two FADs. A low-potential Allochromatium vinosum-type ferredoxin containing two [4Fe-4S] clusters serves as an in vivo electron donor for 4-HBCR. In this work, the oxygen-sensitive proteins 4-HBCR and the ferredoxin (TaFd) from Thauera aromatica were crystallized under anaerobic conditions. 4-HBCR crystallized with PEG 4000 and MPD as precipitant diffracted to about 1.6 A resolution and the crystals were highly suitable for X-ray structure analysis. Crystals of TaFd were obtained with (NH(4))(3)PO(4) as precipitant and revealed a solvent content of 77%, which is remarkably high for a small soluble protein. The structure of TaFd was solved at 2.9 A resolution by the molecular-replacement method using the highly related structure of the ferredoxin (CvFd) from A. vinosum as a model. Structural changes between the two ferredoxins around the [4Fe-4S] cluster can be correlated with their different redox potentials.
