The Design module of DefPred is developed for producing all possible alternate/mutants of the submitted protein sequence using model 1 and model 2. The new peptide is formed by mutating a single residue at a time. It can also provide a prediction score, to identify the peptide which can be defensins. Users can also sort the prediction score to find the highest scored/best mutant peptide, which can be a defensin peptide. Further, the user can also generate several mutant peptides of the given sequence. It allows the user to design the best mutant with the highest score. Please visit Help page, for more information.
