PTMs alter the physicochemical properties of the peptide by altering the electrostatic charge, hydrophilicity, and conformation, thereby modulating their ability to specifically bind to the protein of interest. Some nascent peptide chains can be directly folded into the final three-dimensional structure after being released from the ribosome, but in most cases, the nascent peptide undergoes a series of processing modifications to function. In general, post-translational modifications are for functional needs, and in another case, the need to fold into a natural conformation. https://www.creative-peptides.com/services/post-translational-modification.html |
