Conformational diversity: an essential concept to understand protein biology
The native state of proteins is composed of conformers in a dynamical equilibrium. Here we explored different issues related with conformational diversity using a curated and experimentally based database called CoDNaS. This database is a collection of redundant structures for the same sequence. CoDNaS estimates the degree of conformational diversity using different global and local structural similarity measures. It allows to explore how structural differences among conformers change as a function of several features related with structure estimation (type of structure estimation (NMR, RX), presence of bound ligands, oligomeric change, post-translational modifications, pH, presence of disorder, etc) as well as biological information (biological function, taxonomy, fold class, etc). We have used CoDNaS to explore the influence of protein evolution in conformational diversity, the efect of mutations in different conformers, the distribituion of conformacional diversity in structural space and its relationship with the occurrence of protein disorder.
