'''Solution Structure of ydhR protein from Escherichia coli'''<br />


==Overview==
==Solution Structure of ydhR protein from Escherichia coli==
YdhR is a 101-residue conserved protein from Escherichia coli. Sequence, searches reveal that the protein has &gt;50% identity to proteins found in a, variety of other bacterial genomes. Using size exclusion chromatography, and fluorescence spectroscopy, we determined that ydhR exists in a dimeric, state with a dissociation constant of approximately 40 nM. The, three-dimensional structure of dimeric ydhR was determined using NMR, spectroscopy. A total of 3400 unambiguous NOEs, both manually and, automatically assigned, were used for the structure calculation that was, refined using an explicit hydration shell. A family of 20 structures was, obtained with a backbone RMSD of 0.48 A for elements of secondary, structure. The structure reveals a dimeric alpha,beta fold characteristic, of the alpha+beta barrel superfamily of proteins. Bioinformatic approaches, were used to show that ydhR likely belongs to a recently identified group, of mono-oxygenase proteins that includes ActVA-Orf6 and YgiN and are, involved in the oxygenation of polyaromatic ring compounds.

YdhR is a 101-residue conserved protein from Escherichia coli. Sequence searches reveal that the protein has &gt;50% identity to proteins found in a variety of other bacterial genomes. Using size exclusion chromatography and fluorescence spectroscopy, we determined that ydhR exists in a dimeric state with a dissociation constant of approximately 40 nM. The three-dimensional structure of dimeric ydhR was determined using NMR spectroscopy. A total of 3400 unambiguous NOEs, both manually and automatically assigned, were used for the structure calculation that was refined using an explicit hydration shell. A family of 20 structures was obtained with a backbone RMSD of 0.48 A for elements of secondary structure. The structure reveals a dimeric alpha,beta fold characteristic of the alpha+beta barrel superfamily of proteins. Bioinformatic approaches were used to show that ydhR likely belongs to a recently identified group of mono-oxygenase proteins that includes ActVA-Orf6 and YgiN and are involved in the oxygenation of polyaromatic ring compounds.
