iAlign: a method for the structural comparison of protein–protein interfaces

摘要

Motivation: Protein–protein interactions play an essential role in many cellular processes. The rapid accumulation of protein–protein complex structures provides an unprecedented opportunity for comparative studies of protein–protein interactions. To facilitate such studies, it is necessary to develop an accurate and efficient computational algorithm for the comparison of protein–protein interaction modes. While there are many structural comparison approaches developed for individual proteins, very few methods are available for protein–protein complexes.
