Negative regulation of L-arabinose metabolism in Bacillus subtilis: characterization of the araR (araC) gene.
The Bacillus subtilis araC locus, mapped at about 294 degrees on the genetic map, was defined by mutations conferring an Ara- phenotype to strains bearing the metabolic araA, araB, and araD wild-type alleles (located at about 256 degrees on the genetic map) and by mutants showing constitutive expression of the three genes. In previous work, it has been postulated that the gene in which these mu...
متن کاملProbing key DNA contacts in AraR-mediated transcriptional repression of the Bacillus subtilis arabinose regulon
In the absence of arabinose, the AraR transcription factor represses the expression of genes involved in the utilization of arabinose, xylose and galactose in Bacillus subtilis. AraR exhibits a chimeric organization: the N-terminal DNA-binding region belongs to the GntR family and the C-terminal effector-binding domain is homologous to the GalR/LacI family. Here, the AraR-DNA-binding interactio...
متن کاملAraC protein, regulation of the l-arabinose operon in Escherichia coli, and the light switch mechanism of AraC action.
This review covers the physiological aspects of regulation of the arabinose operon in Escherichia coli and the physical and regulatory properties of the operon's controlling gene, araC. It also describes the light switch mechanism as an explanation for many of the protein's properties. Although many thousands of homologs of AraC exist and regulate many diverse operons in response to many differ...

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
