AAindex: Amino acid indices, substitution matrices and pair-wise contact potentials

AAindex: Amino acid indices, substitution matrices and pair-wise contact potentials
Owning Organization:
Resource classification: Database
Tag (subject)  (1): Protein
Tag (data type)  (1): Sequence
Overview:
The AAindex database collects and organizes amino acid properties. Users can search from dozens of studies summarizing multiple biophysical parameters for three types of information:

- AAindex1: Biophysical properties of individual amino acids. All indexed studies have been compared to other studies in the database and pairwise correlation coefficients between related studies are provided.

- AAindex2: Substitution indices indicating amino acid similarity.

- AAindex3: Pairwise contact potentials between amino acids in various contexts.

All three databases can be searched either by study or keyword using DBGET.
