The PDBFlex database explores the intrinsic flexibility of protein structures by analyzing structural variations between different depositions and chains in asymmetric unit of the same protein in PDB. It allows to easily identify regions and types of structural flexibility present in a protein of interest.
Structures of protein chains with identical sequences (sequence identity > 95%) were aligned, superimposed and clustered. Then global and local structural differences were calculated within these clusters. To query PDBFlex database, please select a cluster from the Clusters list (available via link at the top of the page) or use the search field on the left.
