Splet18. sep. 2024 · Collision between two ribosomes requires them to be separated by exactly a footprint distance on an intact mRNA, and it results in a bond (“!3” in Eq 8) between the f site of the trailing ribosome and the b site of the leading ribosome. The collision rate constant is set equal to the elongation rate at the A site codon of the trailing ribosome. Splet01. apr. 2013 · The largest ribosomal protein, S1, is necessary for translation initiation as well as elongation and purifies in near equimolar amounts with RNAP. Interestingly, …
