Selective Cleavage of Isoaspartyl Peptide Bonds by Hydroxylamine after Methyltransferase Priming

Formation of atypical isoaspartyl (isoAsp) sites in peptides and proteins via the deamidation-linked isomerization of asparaginyl-Xaa bonds or direct isomerization of aspartyl-Xaa bonds is a major contributor to spontaneous protein damage under mild conditions. This nonenzymatic reaction reroutes th...
