Proton magnetic resonance spectra of methylthiohydantoin (3-methyl-2-thiohydantoin), thiohydantoin (2-thiohydantoin), and hydantoin derivatives of amino acids were studied in dimethyl sulfoxide-d6. Their parent amino acids could be identified by the spectra. An application to the N- and C-terminal amino acid analysis of a tripeptide was examined.

Quantitative N-terminal peptide-bond hydrolysis with the cis-beta-hydroxyaquo(triethylenetetramine) cobal (III) ion, i.e. β-[Co(trien)(OH)(OH2)]2+, is reported. The method has been demonstrated with 20 small peptides, a hexapeptide, bradykinin, insulin A chain (oxidized), glucagon and insulin. The procedure involves no acidic hydrolysis step and thus no destruction of labile amino acids.

Proton magnetic spectra of 3-phenyl-2-thiohydantoin derivatives of common amino acids in deuterated dimethyl sulfoxide were recorded. Spectral data pertaining to characteristic protons for diagnostic purpose were compiled. Their application to the N-terminal amino acid analysis of peptide by Edman degradation was examined.
