QSPepDesign is a prediction tool which allows users to design Quorum sensing peptides by developing all possible mutants of a given peptide to predict Quorum sensing(QS) ability of designed peptides. It also provide information related to important user defined physico-chemical properties. Along with this after designing and generating mutants user can further select peptide mutant to generate other possible mutants and predict their activity. User can also download results by clicking icon. For more information click .
