Characterizing degradation products of peptides containing N‐terminal Cys residues by (off‐line high‐performance liquid chromatography)/matrix‐assisted laser desorption/ionization quadrupole time‐of‐flight measurements
A transformation analogous to the well‐known conversion of an N‐terminal glutamine residue to pyroglutamic acid is the cyclization of an N‐terminal carboxamidomethylated cysteine residue (the normal product of alkylation with iodoacetamide). This yields 5‐oxothiomorpholine‐3‐carboxylic acid, with th...
