AAindex is a comprehensive database for amino acid indices and mutation matrices. It provides numerical data on amino acid properties and similarities, accessible online or via FTP.

Area of Science:

  • Bioinformatics
  • Molecular Biology
  • Biochemistry

Background:

  • Amino acid indices represent biochemical and physicochemical properties.
  • Amino acid mutation matrices quantify amino acid similarity.
  • Databases are crucial for organizing and accessing biological data.

Purpose of the Study:

  • To present AAindex, a database of amino acid indices and mutation matrices.
  • To provide a centralized resource for researchers studying amino acid properties.

Main Methods:

  • Compilation of published amino acid indices (AAindex1).
  • Compilation of published amino acid mutation matrices (AAindex2).
  • Inclusion of definitions, references, correlation coefficients, and data for each entry.

Main Results:

  • AAindex database established with two sections: AAindex1 and AAindex2.
  • Each entry contains comprehensive information including data and related entries.
  • Database is accessible via GenomeNet and anonymous FTP.

Conclusions:

  • AAindex serves as a valuable resource for bioinformatics and molecular biology research.
  • Facilitates the study of amino acid properties and relationships.
  • Ensures broad accessibility for the scientific community.
