VAST, short for Vector Alignment Search Tool, is a computer algorithm developed at NCBI and used to identify similar protein 3-dimensional structures by purely geometric criteria, and to identify distant homologs that cannot be recognized by sequence comparison.VAST is applied on every protein in the Molecular Modeling Database (MMDB) during MMDB data processing in order to identify similar 3D structures.
