Are stop codons recognized by base triplets in the large ribosomal RNA subunit?
The precise mechanism of stop codon recognition in translation termination is still unclear. A previously published study by Ivanov and colleagues proposed a new model for stop codon recognition in which 3-nucleotide Ter-anticodons within the loops of hairpin helices 69 (domain IV) and 89 (domain V) in large ribosomal subunit (LSU) rRNA recognize stop codons to terminate protein translation in ...

متن کاملRNA-magnesium-protein interactions in large ribosomal subunit.
Some of the magnesium ions in the ribosome are coordinated by multiple rRNA phosphate groups. These magnesium ions link distal sequences of rRNA, primarily by incorporating phosphate groups into the first coordination shell. Less frequently, magnesium interacts with ribosomal proteins. Ribosomal protein L2 appears to be unique by forming specific magnesium-mediated interactions with rRNA. Using...
