?Original VAST
Original VAST finds structures that are similar to individual protein molecules, or individual 3D domains, in your query structure. Select a protein molecule ("chain") or 3D domain of interest from the table below to view a list of other proteins or domains that have a similar 3D shape. In contrast to VAST+, which focuses on the default biological unit, Original VAST lists all protein molecules in the asymmetric unit of the query structure.
