Three-dimensional crystal structure of dissimilatory sulfite reductase D (DsrD)
Overview
The crystal structure of DsrD from Desulfovibrio vulgaris Hildenborough, has been determined at 1.2 A resolution. DsrD is in a dimeric form in the, crystal, and five sulfate anions were located on the surface. The, structure of DsrD comprises a winged-helix motif, which shows the highest, structural homology to similar motifs found in Z-DNA binding proteins and, some B-DNA binding proteins. The core structure of the molecule is, constructed by intramolecular interactions of hydrophobic residues, which, are well conserved in DNA binding proteins, suggesting that these proteins, belong to the same superfamily on the basis of the structure. These, results indicate a possible role of DsrD in transcription or translation, of genes for enzymes catalyzing dissimilatory sulfite reduction.
