bookmark PinaColada Provides functions for inhibitory peptide design. PinaColada extracts a suitable initial peptide from one protein of a protein–protein complex couple, with high affinity to bind to the other. It employs the Ant Colony Optimization algorithm for the optimization task. This tool provides three modes: A Protein–Peptide, a Protein–Protein mode and Protein-Binding site mode. It can be useful to minimize the search space of inhibitory peptide.
