Improving Translational Accuracy

11.6K
Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Summary
This summary is machine-generated.

Accurate error rate estimation is crucial for single molecule protein sequencing (SMPS) technologies. We developed two methods, including a Hidden Markov Model (HMM) approach, to accurately estimate SMPS error rates for fluorosequencing applications.
