Background Information
Rsp1275 is a member of the Fnr-Crp family of transcriptional regulators. Homologues of the Fnr protein from E. coli have been identified in a variety of taxonomically diverse bacterial species. The bacterium Rhodobacter sphaeroides 2.4.1 encodes 8 members of this family, however only 2 have known function. The modeling of 7 of them were successfully obtained using 3D-Jigsaw, all being very similar in structure to Crp (the only one with crystal structure solved). The DNA binding domain helix-turn-helix is located in the C-terminal, and the N-terminal part contains the allosteric effector domain. Rsp1275 has been linked with salt-tolerance in Rhodobacter spheroides. Different genes coding for the Fnr-Crp proteins of unknown function have been cloned and a multicopy test was performed to evaluate these as potential regulators of NaCl-responsive genes.
