Welcome to Natural Peptides Module for Beginners

This module is used to predict the tertiary structure of peptides having natural amino acids. A user needs to submit the peptide sequence in the text box along with the email address. An example sequence can be used by clicking on the 'Example Sequence' button. For further analysis, users can select the advanced options given below. For more information click help
