36-113 1.09e-45

AraC/XylS family transcriptional regulators similar to Escherichia coli MelR, N-terminal cupin domain; This family contains bacterial proteins containing an AraC/XylS family helix-turn-helix (HTH) DNA-binding domain C-terminal to a cupin domain, and may be possible transcriptional regulators, including Escherichia coli MelR, a transcription factor that controls melibiose utilization. MelR is encoded by the melR gene and is essential for melibiose-dependent triggering of the melAB operon that encodes products needed for melibiose catabolism and transport. Expression of melR is autoregulated by MelR, which represses the melR promoter by binding to a target that overlaps the transcript start. Proteins in this family belong to the cupin superfamily with a conserved "jelly roll-like" beta-barrel fold capable of homodimerization.

208-249 1.59e-06

Bacterial regulatory helix-turn-helix proteins, AraC family; In the absence of arabinose, the N-terminal arm of AraC binds to the DNA binding domain (pfam00165) and helps to hold the two DNA binding domains in a relative orientation that favours DNA looping. In the presence of arabinose, the arms bind over the arabinose on the dimerization domain, thus freeing the DNA-binding domains. The freed DNA-binding domains are then able to assume a conformation suitable for binding to the adjacent DNA sites that are utilized when AraC activates transcription, and hence AraC ceases looping the DNA when arabinose is added.
