概要

• 論文の詳細を見る

• Positive fast atom bombardment tandem mass spectrometry (FAB-MS/MS) was applied for peptide sequencing, particularly for determining the gamma glutamyl linkage involved in metal-binding peptides such as Cadystin (γEC)_3G=Cadystin A and Cadystin (γEC)_2G=Cadystin B (MW 771 and 539, respectively). The fragmentation patterns between the natural gamma glutamyl peptide and the synthetic alpha glutamyl one were clearly distinguishable. FAB-MS/MS was proved to be a good method for determining these peptides, since it needed no chemical degradation and only a small amount of the peptide was needed for determination.
