AA(Amino-Acid) Index Descriptors

 

This module has been developed to calculate AA-Index properties of submitted protein or peptide sequence(s), where users are allowed to paste or upload file with multiple protein/peptide sequences [fasta format or single line sequnces] similar to the Example sequence. The user can also provide the PDB or UniProt IDs in the mentioned format. The amino acid properties used here are various types of amino acids indices available at (https://www.genome.jp/dbget/AAindex/list_of_indices). User has to choose aaindex for the descriptors calculation.

*In order to calculate amino acid index properties for all indices, kindly use the standalone version of Pfeature, available at this link, as calcuation of this feature for all indices is a time-consuming task.

For more information see HELP page.

Paste peptide sequence(s) in single line format or FASTA format:
OR Submit sequence file: 
OR PDB IDs:      
OR UniProt IDs: 
  • Select portion of Sequence:
    • This section allow users to select either complete or specific portion of the seqeunce, such as

      1. Whole: Performs operation on complete sequence
      2. N-Term: This allows to cut the user specified portion from N-terminal of the sequence
      3. C-Term: This allows to cut the user specified portion from C-terminal of the sequence
      4. Split: This allows users to split the sequence into fragments and performs calculation indepedently
      5. Rest: This allows users to drop the residues from N- and C-terminal and performs calculation on the remaining fragment
Whole   N-Term        C-Term       Split       Rest:    N-term   C-term
