Charges belonging to atoms inherited from K1 Cagri were removed, and their sum (0.049e) was equally redistributed to the seven sp 3 carbon atoms bound to the terminal carboxy group to restore formal charge -1
At the C-terminus, a proline amidation replaces the native amylin residue, enhancing resistance to proteolytic degradation
