Almost all bacteria use a mechanism known as trans-translation to rescue stalled … schwintek cableWebb10 apr. 2014 · Bacterial cells have evolved processes that enable ribosomes to progress in the absence of codon decoding. Because these processes generally take place when a ribosome is abnormally stalled by the lack of binding of a molecule to the A site, they are termed ribosome rescue processes. prana zion shorts menWebbThese rescue pathways are important for both bacterial physiology and pathogenesis, but have been missed in the eukaryotes, so these may serve as promising targets for developing novel antibiotics.
