Building on PDBe-KB to chart and characterize the conformational landscape of native proteins

31 May 2021 - 30 May 2023

This implementation study will create infrastructure to chart the experimentally sampled conformational diversity of native proteins by exploiting data from the PDB, augmented with results of state-of-the-art computational tools. By integrating resources and tools, workflows will be developed to:

  • compare and cluster different conformations adopted by homologs of the same protein and
  • identify protein regions with different flexibility properties. 

Pipelines will be created to characterize conformational ensembles in terms of:

  • the types of motions described (thermal fluctuations; collective motions) and
  • their functional relevance, using sequence information and functional annotations.

These data will be integrated into the PDBe Knowledge Base and presented in the aggregated views (PDBe is an ELIXIR-Core-Data-Resource), which are freely available to the scientific community. Applications of these new capabilities will be explored in a joint gap analysis with the IDP and Proteomics Communities, including joint meetings, in order to identify future implementations that best serve ELIXIR goals.

This study features the participation of nine ELIXIR Nodes: ELIXIR Norway, ELIXIR France, ELIXIR Spain, ELIXIR UK, EMBL-EBI, ELIXIR Belgium (Wim Vranken, Shoshana Wodak), ELIXIR Denmark, ELIXIR Hungary, and ELIXIR Italy.
