Welcome to PTMs of Residue Module for Beginners

It provides an easy alternative to incorporate PTMs in the peptide. A user only needs to enter the peptide sequence and his/her email address. After submission, a user friendly interface in the tabular form is displayed in which each amino acid of the input peptide sequence is present in one column and a drop down menu of all possible PTMs occur in the next column.
