    Protein Summary

    The Reut_B4095 gene from Ralstonia eutropha jmp134 encodes the YP_298295 protein, a member of the Rrf2 family of transcription regulators (e-val=0.0003) (PF02082). It has sequence similarity to the transcriptional regulator group (COG1339). The homolog gene in R. eutropha H16 strain is predicted to have a functional link by neighborhood association (score 0.87) with a transcriptional regulator of the MocR family.

    2obp structure belongs to the SCOP "winged-helix" superfamily and shows structural similarity to other transcription regulators of the same fold (e.g. DALI Z-score 12.9, rmsd 1.8 Å over 78 residues, 17% identity with PDB id: 2QVO; DALI Z-score 11.8, rmsd 2.0 Å over 73 residues, 27% identity with PDB id: 3CJN, a transcriptional regulator of the MarR family).

    Both homology and structural similarity suggest the protein may function, like MarR, as part of a resistance system.
