Webb11 apr. 2007 · This variation may be caused by the MicF effect on ompF mRNA; similarly MicC may have the same effect on ompC mRNA stability. In contrast, it is important to note that the level of ompF mRNA and ompC mRNA of TET exposed cells remained, at least, similar to that observed for the untreated control (ratio of 1 at 10 mg/L of TET). Webb28 juli 2016 · micF is a stress response gene found in E. coli and related bacteria. It post-transcriptionally controls the expression of the outer membrane porin gene ompF by encoding a trans-asRNA (93 nt) that binds its target ompF mRNA and regulates ompF expression by inhibiting translation and inducing degradation of the message .

WebbExperiments that use ompF-ompC chimeric genes demonstrate that a tolC mutation exerts its effect at either the promoter or the amino-terminal end of the ompF gene. Direct … WebbTo analyze the function of micF as an antisera RNA in the osmoregulatory expression of the ompF gene in Escherichia coli, we performed two experiments. In the first …
WebbThe micF gene encodes a non-translated 93 nucleotide antisense RNA that binds its target ompF mRNA and regulates ompF expression by inhibiting translation and inducing … Webb5 nov. 2016 · We also proposed that while the RNA duplex formation causes premature ompF mRNA transcription termination, it also destabilizes the ompF mRNA. It should be noted that this is the first time that the term ‘interfering’ was used to specifically identify the function of a small RNA to inhibit mRNA translation. This was 14 years earlier than ...
WebbPhosphorylated OmpR (OmpR-P) functions as an activator for ompC but as a repressor of ompF. OmpR-P is also an activator of micF, encoding a small regulatory anti-sense RNA that negatively... Webb24 aug. 2012 · Abstract. Motivation: Regulatory, non-coding RNAs often function by forming a duplex with other RNAs. It is therefore of interest to predict putative RNA–RNA duplexes in silico on a genome-wide scale. Current computational methods for predicting these interactions range from fast complementary-based searches to those that take …
WebbMicF, is a paradigmatic sRNA that acts as a post-transcriptional repressor through imperfect base pairing with the 5′-UTR of its target mRNA, ompF, in Escherichia coli. …

Multiple Choice MicF RNA is not transcribed allowing a stem-loop structure to form at the site of translation initiation MicF RNA is transcribed and base pairs with the OmpF mRNA at the ribosome binding site and enhances translation of the OmpF porin protein MicF RNA is … edenpure living stone cookwareWebbpreviously suggested that the first 13 nucleotides of MicF could suffice for ompF regulation (Papenfort et al., 2010). Here, we provide evidence that the conserved 5′ end of MicF is a seed pairing domain that regulates additional targets at the level of translation, mRNA stability, or both. New MicF targets were predicted experimentally using a edenpure marble coated cookwareWebbThe aims of this research were to study first, the intactness of micF and then quantify the expression of ompF in ciprofloxacin and tetracycline resistant mutants of E. coli. For this purpose the 5' end of micF was amplified and then sequenced. None of these mutants except one and its clone has a mutation in this gene. edenpure infrared heater consumer reportWebbMicF is defined as a canonical trans -encoded sRNA that regulates outer membrane protein F (OmpF) synthesis in Escherichia coli and other related bacteria ( Andersen et al., 1989 ). Approximately 20 nt of MicF forms a perfect RNA duplex by directly pairing with the Shine-Dalgarno region of the ompF mRNA. cone type clutchWebbAmong these, MicF and MicC are the two major sRNAs that modulate the expression of OmpF and OmpC, respectively. They suppress porin expression by base pairing with … edenpure® mighty mini heater
