Welcome to Peptide Cyclization Module for N-C cyclization

This page is designed to predict the peptide structure with N-to-C terminal cyclization. The peptide is made cyclic by incorporating a bond between Nitrogen atom of N-terminal residue and Carbon atom of C-terminal residue. For more information click help
