Welcome to Natural Peptides Module for Experts

This module predicts the tertiary structure of peptides having natural amino acids. It also gives the facility to the users to design the peptides with desirable restraints like specific secondary structure in specific region of the peptide. In the next step, a user can specify the region of the peptide to adopt specific secondary structure or dihedral angles. For more information click help
