Webb1 apr. 2000 · In both systems, expression downstream of the leader occurred via ribosomal shunt under the control of a stable stem and a small ORF preceding it. Shunting … Webb20 juni 2006 · One postulated mechanism involves ribosomal shunting, in which ribosomal subunits completely bypass regions of the 5′ leader. For some mRNAs, shunting has been shown to require various mRNA elements, some of which are thought to base pair to 18S rRNA; however, the role of base pairing has not yet been tested directly.

Webb29 juni 2024 · ( F) Ribosomal shunting: cauliflower mosaic virus (CaMV) ribosomal shunt is shown; the highly structured region promotes shunting of the 40S from the “donor” site to a downstream “acceptor” site for initiation. 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. 5巡目
