Specificity quantification of biomolecular recognition and its implication for drug discovery.

ABSTRACT: Highly efficient and specific biomolecular recognition requires both affinity and specificity. Previous quantitative descriptions of biomolecular recognition were mostly driven by improving the affinity prediction, but lack of quantification of specificity. We developed a novel method SPA (SPecificity and Affinity) based on our funneled energy landscape theory. The strategy is to simultaneously optimize the quantified specificity of the "native" protein-ligand complex discriminating against "non-native" binding modes and the affinity prediction. The benchmark testing of SPA shows the best performance against 16 other popular scoring functions in industry and academia on both prediction of binding affinity and "native" binding pose. For the target COX-2 of nonsteroidal anti-inflammatory dru
