چکیده
The roles of the first base of the Pribnow box in positive regulation of the ompC and ompF genes were studied. G- and A-to-T substitutions of the first base of the ompC and ompF Pribnow boxes, respectively, resulted in a high-level functioning of the promoters in the ompR background. The level was further enhanced significantly in the ompR+ background. The effects of other substitutions were also studied. Based on these observations, the roles of the Pribnow box in the positive regulation are discussed.

Cloning and sequencing of ompf Salmonella typhi Salmonella ompf gene in Escherichia coli Origami
Background and Aim: Salmonella Typhi belongs to the family Enterobacteriaceae, gram-negative bacilli and causes gastrointestinal diseases such as typhoid. This bacterium has a special structure and various genes, including the ompf gene (outer membrane protein). Recent studies have shown the possibility of using ompf in the development of a diagnostic tuberculosis vaccine. Therefore, the aim of...
متن کاملHeterologous expression of Escherichia coli porin genes in Salmonella typhi Ty2: regulation by medium osmolarity, temperature and oxygen availability.
Electrophoretic analysis of outer membrane proteins showed that Salmonella typhi OmpC expression is not reciprocally regulated relative to OmpF as described for Escherichia coli and S. typhimurium. When bacteria were grown in minimal media, both OmpC and OmpF were repressed as the osmolarity increased. However, in Luria broth, expression of OmpC was slightly induced by osmolarity up to 0.3 osmM...
متن کاملPurification and characterization of the OmpR protein, a positive regulator involved in osmoregulatory expression of the ompF and ompC genes in Escherichia coli.
The OmpR protein is a positive regulator involved in osmoregulatory expression of the ompF and ompC genes, which respectively code for major outer membrane proteins OmpF and OmpC of Escherichia coli. The OmpR protein has been purified to homogeneity from an overproducing strain harboring an ompR gene-carrying plasmid. Throughout the purification the OmpR protein behaved as a single entity. The ...
متن کاملInteraction of a transcriptional activator, OmpR, with reciprocally osmoregulated genes, ompF and ompC, of Escherichia coli.
The ompB locus, comprised of the genes ompR and envZ, regulates the expression of the genes ompF and ompC that encode the major porin proteins in the outer membrane of Escherichia coli K-12. OmpR is believed to activate transcription of ompF and ompC in a reciprocal manner depending upon the osmolarity of the culture medium. We were able to purify OmpR to homogeneity and to characterize its int...
متن کاملActivation of the osmoregulated ompC gene by the OmpR protein in Escherichia coli: a study involving synthetic OmpR-binding sequences.
Expression of the Escherichia coli outer membrane proteins, OmpC and OmpF, is regulated in response to the medium osmolarity. The OmpR and EnvZ proteins are transcriptional factors involved in this osmotic regulation of the ompC and ompF genes. In particular, expression of the ompC gene is activated by the positive regulator, OmpR, in response to high osmolarity of the medium. In this study, we...
