Insights

Messenger RNA (mRNA) sequences influence protein folding rates. Adjacent base information redundancy and GC content negatively correlate with folding rates, while single base information redundancy positively correlates.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Bioinformatics

Background:

  • Protein folding rates are known to be influenced by amino acid sequences and protein structures.
  • The relationship between messenger RNA (mRNA) sequences and protein folding rates remains largely unexplored.

Purpose of the Study:

  • To investigate the correlation between mRNA sequence characteristics (genetic language parameters) and protein folding rates.
  • To determine if mRNA sequence information is crucial for predicting protein folding rates.

Main Methods:

  • Linear regression analysis was employed to examine the relationship between mRNA sequence parameters and protein folding rates.
  • Key mRNA parameters analyzed included adjacent base-related information redundancy (D2), single base information redundancy (D), and GC content.

Main Results:

  • Significant negative correlations were found between D2 values and GC content of mRNA sequences with protein folding rates.
  • A significant positive correlation was observed between D values of mRNA sequences and protein folding rates.
  • The identified relationships varied across different protein groups, suggesting protein-specific regulatory mechanisms.

Conclusions:

  • mRNA sequence features, beyond protein structure and amino acid sequence, provide essential information for understanding and predicting protein folding rates.
  • Genetic language parameters derived from mRNA sequences are significant regulators of protein folding dynamics.
  • Incorporating mRNA sequence information can improve the accuracy of protein folding rate predictions.

Protein Folding

Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.

RNA Stability

Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

Molecular Chaperones and Protein Folding

The native conformation of a protein is formed by interactions between the side chains of its constituent amino acids. When the amino acids cannot form these interactions, the protein cannot fold by itself and needs chaperones. Notably, chaperones do not relay any additional information required for the folding of polypeptides; the native conformation of a protein is determined solely by its amino acid sequence. Chaperones catalyze protein folding without being a part of the folded protein.

Improving Translational Accuracy

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...
