Mass spectrometry has been applied to determine the deamidation sites and the aggregation region of the deamidated human islet amyloid polypeptide (hIAPP). Mutant hIAPP with iso-aspartic residue mutations at possible deamidation sites showed very different fibril formation behaviour, which correlates with the observed deamidation-induced acceleration of hIAPP aggregation.
