Conjoint Triad Descriptors (CTD)

This tool calculates the conjoint triad descriptors of the protein sequences/ sub-sequences. Amino acids are classified into seven groups based on the various properties. Triads of these seven groups are used for the interpretation of results. User may type the sequence or upload the file of sequences in single line or FASTA format. The user can also provide the PDB or UniProt IDs in the mentioned format.For more information see HELP page.

Paste peptide sequence(s) in single line format or FASTA format:

This section allow users to select either complete or specific portion of the seqeunce, such as

Whole: Performs operation on complete sequence
N-Term: This allows to cut the user specified portion from N-terminal of the sequence
C-Term: This allows to cut the user specified portion from C-terminal of the sequence
Split: This allows users to split the sequence into fragments and performs calculation indepedently
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-ter C-ter
