Reduced (redundant or simplified) Alphabets for Proteins
This tool was originally created to reduce protein sequences by grouping the aminoacids in classes. During its development code to retrieve sequences with colours was added. Additionally, each aminoacid may be displayed with a distinct colour (without applying reductions).
The reduced aminoacid alphabets has been obtained from the references bellow:
