** *Dear colleagues,* * We have expanded the superposition process at the PDBe-KB aggregated views of proteins to allow superposition of the predicted model from the AlphaFold Protein Structure Database (AlphaFold DB). This new feature loads the model from AlphaFold DB on demand and superposes it to the equivalent PDB structures, using the superposition functionality through the Mol* molecular viewer. This allows easy comparison of the different conformational states of a given protein in the PDB with the models predicted in AlphaFold DB, to identify if the predicted model represents a specific conformational state. You can view the structure superposition for a specific protein (per UniProt accession) at the PDBe-KB aggregated views of proteins (pdbekb.org/protein). The superposition can be accessed from the Summary or Structures tabs using the green buttons labelled ‘3D view of superposed structures’.
