Abstract
The long-term goal of this project is to develop methods to predict the functional regions of proteins of unknown function. The results of previous studies have suggested that one of the largest pockets on a protein surface is most likely to be the ligand binding site. We tested if adding a measure related to local flexibility would make this prediction more accurate. We tested the hypothesis that considering the relative X-ray crystallographic B-factors (temperature factors) of atoms in a protein structure in addition to the relative sizes of surface pockets can help in identifying the functional regions of proteins.

We further confront these results with binding affinities calculated for ultradiluted conditions by means of free-energy perturbation (FEP) calculations
We examined the effect of polyethylene glycol (PEG) on protein-complex stability at 298 K
Summary
236-Pos Polyethylene Glycol Size and Protein-Complex Stability Francis J. Protein - ligand interactions and their good understanding are necessary for rational structure-based drug design. It is currently not possible to design a high-affinity and high-specificity small molecule compound based on the protein structure alone.
