Welcome to Terminal Modification Module for Structure Modification

This module is used to input an already available peptide tertiary structure in PDB file format and subsequently if a structure contains any N-terminal and C-terminal Modifications user can choose the appropriate options which is given below to modify its structure. For more information click help
