If you have a newly determined protein structure that is not yet in MMDB, then you can use the
||view the "show annotation" graphic for any protein molecule of interest on a structure summary page, then click on the bar graphic for the overall protein molecule or for any 3D domain it contains in order to view a list of structures that are similar in shape to the molecule or 3D domain you selected. The VAST Help document provides additional details and illustrated examples.
||follow the link for "Similar Structures: VAST" in the upper right corner of a structure summary page to open a tabular list of the protein molecules and 3D domains in the structure. Then select the protein or 3D domain of interest to view a list of structures that are similar in shape to the region you selected.
