A method for assessing the size of a protein from its composition: a correction
A computer method for estimating protein size from amino acid data had a calculation error. This error did not lead to incorrect size estimates but rather a wider range of possible sizes for virus proteins.
Area of Science:
- Biochemistry
- Computational Biology
- Virology
Background:
- A prior publication detailed a computational method for protein size assessment using amino acid composition.
- This method was applied to analyze virus protein data.
Purpose of the Study:
- To correct a previously published arithmetical formula used in a protein size estimation method.
- To clarify the impact of the formula error on the analysis of virus protein data.
Main Methods:
- Review and correction of the published arithmetical formula for protein size calculation.
- Re-evaluation of the application of the corrected formula to virus protein data.
Main Results:
- An error in the published arithmetical formula for protein size assessment was identified.
- The identified error does not produce incorrect protein size estimates.
Conclusions:
- The error in the formula leads to a more equivocal range of possible protein sizes rather than inaccurate ones.
- Accurate protein size estimation from amino acid composition requires the corrected formula.
