==Crystal Structure of Trichomonas vaginalis Ferredoxin==
-
Crystallographic studies revealing the three-dimensional structure of the, oxidized form of the [2Fe-2S] ferredoxin from Trichomonas vaginalis (TvFd), are presented. TvFd, a member of the hydrogenosomal class of ferredoxins, possesses a unique combination of redox and spectroscopic properties, and, is believed to be the biological molecule that activates the drug, metronidazole reductively in the treatment of trichomoniasis. It is the, first hydrogenosomal ferredoxin to have its structure determined. The, structure of TvFd reveals a monomeric, 93 residue protein with a fold, similar to that of other known [2Fe-2S] ferredoxins. It contains nine, hydrogen bonds to the sulfur atoms of the cluster, which is more than the, number predicted on the basis of the spectroscopic data. The TvFd, structure contains a large dipole moment like adrenodoxin, and appears to, have a similar interaction domain. Our analysis demonstrates that TvFd has, a unique cavity near the iron-sulfur cluster that exposes one of the, inorganic sulfur atoms of the cluster to solvent. This cavity is not seen, in any other [2Fe-2S] ferredoxin with known structure, and is hypothesized, to be responsible for the high rate of metronidazole reduction by TvFd.
