Chameleon Sequences (exact match of ‘probe’ with ‘target’) (CHAMPEP-EXACT)
This database contains information on all ‘chameleon’ peptides that have identical sequence but different conformations in proteins. In this database, the ‘probe’ peptide is of fixed length and the ‘target’ peptide is ALSO of fixed length. The fixed length starts with peptides comprising six residues (i.e., hexapeptides). One can use this database, by specifying a hexapeptide or larger sequence to identify whether it has been observed as a ‘chameleon’ peptide in proteins, i.e., whether it is observed as a helix in strand, helix in coil or strand in coil.
