Chemical ionization mass spectrometry of complex molecules—VI: Peptides†
The chemical ionization mass spectra of a series of simple peptides containing six or fewer amino acids have been studied. Using methane as the reactant gas we found cleavage of the peptide bond… Expand
Determination of the amino acid sequence of peptides using dipeptidyl aminopeptidases
Another method involving digestion of the starting peptide with dipeptidyl aminopeptidase I (DAP I) to give a mixture of diPEptides and esterification and trifluoroacetylation of thedipeptide methyl esters is described, resulting in mass spectrometric determination of the amino acid sequence in peptide derivatives.

Butylation of the tryptophan indole ring: a side reaction during the removal of t-butyloxycarbonyl and t-butyl protecting groups in peptide synthesis
The butylation of tryptophan residues during the trifluoroacetic acid catalysed removal of the t-butyloxycarbonyl and t-butyl protecting groups of peptides is reported.
The structure of enniatins and related antibiotics.
Abstract The synthesis of cyclotetradepsipeptides the structure of which has previously been assigned to antibiotics of the enniatin group is described. It was found that these antibiotics cannot be… Expand
Total synthesis of sporidesmolide I
Abstract The first total synthesis of natural cyclodepsipeptide, namely sporidesmolide I, has been achieved and thus an unambiguous proof of its structure has been given.
Mass spectrometric study of cyclodepsipeptides. Fragmentation types of regular and irregular cyclohexadepsipeptides.
Mass spectrometric study of cyclodepsipeptides
Mass spectrometric amino acid sequence determination in arginine-containing peptides.
The modified peptides undergo the amino acid type of fragmentation, so that mass spectrometry can now be used for amino acid sequence determination in arginine-containing peptides. Expand

It has been shown earlier by us and by others that mass spectrometry can be used for the elucidation of the primary structure of peptides containing residues of all the ammo acids commonly found in… Expand
Comparative studies on photo‐ionization and electron‐impact ionization of peptide derivatives
Photo-ionization (PI) mass spectrometry performed with a monochromatic photon beam was applied to a series of peptide derivatives. PI mass spectra of ten N-acylpeptide methyl esters containing two to… Expand
