WebbRibosomal shunting is a translation initiation depending on cap-dependent discontinuous scanning, where ribosomes are loaded onto mRNA at the 5'-cap structure, start scanning … Webb7 juli 2010 · Ribosome shunting, best described in cauliflower mosaic virus, is an adapted form of reinitiation ( 25 ). Following translation termination of a short uORF, the 40S ribosomal subunit encounters a stable secondary structure and is shunted to an internal position normally located at, or slightly upstream of, an internal AUG codon ( 26 ). ibis budget edinburgh park postcode

Webb15 okt. 2006 · The results of our systematic mutational, structural and functional analysis of the 5′ UTR led us to conclude that a ribosome-shunting mechanism - rather than leaky scanning, ribosomal reinitiation, or internal ribosome entry site (IRES)-mediated initiation - controls the translation of regA mRNA. Webb20 feb. 2008 · Ribosome shunt is a mechanism of eukaryotic translation initiation that combines features of both 5′-end dependent scanning and internal ribosome entry. It has been discovered in plants, first for Cauliflower mosaic virus (CaMV) [1], [2] and then for Rice tungro bacilliform virus (RTBV) [3]. ibis budget fes fes moroccoWebbRibosome shunting functions in a mammalian cell-free translation system To investigate whether the shunt mechanism promoted by the CaMV leader can function in the absence of plant- specific translational factors, we used rabbit reticulocyte lysate (RRL) for in vitro translation experiments. ibis budget el jadida location

WebbThus, the relative importance of anaerobic ammonium oxidation and denitrification in N(2) production appears to be regulated by the availability of their reduced substrates. By shunting nitrogen directly from ammonium to N(2), anaerobic ammonium oxidation promotes the removal of fixed nitrogen in the oceans.
