Welcome to D-amino acids Module for Experts

This module is used to predict the tertiary structure of peptides having D-amino acids. A user can submit the sequence in the box provided below. If a sequence contains amino acid letter in small alphabets, then it will be considered as D-amino acid. Alternatively, position of D-amino acids can also be entered in the box provided. If a user wants to incorporate multiple D-amino acids, then user should enter the positions separated by comma (,). For more information click help
