Filters for Globular Protein Evaluation
Packing Fraction
The formation of secondary and tertiary structures in proteins drives them towards achieving high packing densities. We use a grid based method to compute the packing fraction of proteins. A distribution of packing faction for a dataset of ~1000 representative proteins from PDB database is generated (fig). This filter can be employed to evaluate the value of packing fraction for a given protein and to find out whether the value is in acceptable limits for globular proteins or not.
