Estimating structure quality trends in the Protein Data Bank by equivalent resolution
A method to estimate equivalent resolution for protein structures is presented. A time-trend in the PDB structures quality for the methods is compared. All five methods show significantly higher e-resolutions for smaller proteins. The predictions improved on modeling with 1/log(size) instead of size. Over 22,000 X-ray structures were used for training this model.
