PSST-2.0 is an enhanced web-based search tool for retrieving protein and nucleic acid sequence data from the Protein Data Bank. It provides up-to-date information and detailed outputs for 3-D protein structures.

Area of Science:

  • Bioinformatics
  • Structural Biology

Background:

  • PSST-2.0 is an updated version of the Protein Sequence Search Tool (PSST).
  • It is a web-based, interactive search engine for accessing protein and nucleic acid sequence information.

Purpose of the Study:

  • To provide an efficient tool for retrieving sequence data and related details from the Protein Data Bank (PDB).
  • To offer search capabilities on selected subsets of non-homologous protein chains (25% and 90%).

Main Methods:

  • Utilizes a locally maintained PDB database, updated weekly.
  • Accepts user-uploaded 3-D atomic coordinates in PDB file format for detailed analysis.
  • Web-based interface for interactive searching.

Main Results:
