Research Abstract |
Proteins produced in biological systems assume well-defined structures to obtain their unique functions. However, there are many intrinsically disordered proteins (IDPs) which are unable to form specific structures by themselves in genomic sequences. IDPs form well-ordered structures upon binding to their specific ligands. Here, we analysed physicochemical mechanism of ligand binding by EspB, an IDP pathogens from enterohaemorrhagic E. coli. We found that EspB binds to alpha-catenin through the unstable alpha-helical regions formed around G41-E70 in a manner of "Conformational Selection".
