Differentiation of leucine and isoleucine residues in peptides by consecutive reaction mass spectrometry
Autor: Takemichi Nakamura, Takeshi Kinoshita, Yasuko Ohki, Hidemi Nagaki
Publikováno v: Analytical Chemistry. 62:311-313
In this paper, we present a new strategy that is widely applicable for the assignment of leucine and isoleucine in peptide moledules. First, the peptides (or proteins) are digested with an endopeptidase, thermolysin. Second, the proteolytic digest is

Publikováno v: Glycobiology. 8(6)
The polysaccharide chains of enterobacterial common antigen (ECA) consist of linear trisaccharide repeat units with the structure -->3)-alpha-d-Fuc4NAc-(1-->4)-beta-d-ManNAcA-(1--> 4)-alpha-d-GlcNAc-(1-->, where Fuc4NAc is 4-acetamido-4, 6-dideoxy-d-

Matlystatins, new inhibitors of type IV collagenases from Actinomadura atramentaria. III. Structure elucidation of matlystatins A to F
Autor: Takeshi Ogita, Kazuhiko Tamaki, Yoshiko Ohkuma, Hidemi Nagaki, Hideyuki Haruyama, Takeshi Kinoshita
Publikováno v: The Journal of antibiotics. 47(12)
The structures of matlystatins, novel type IV collagenase inhibitors isolated from Actinomadura atramentaria, have been determined by a systematic application of homo- and heteronuclear 2D NMR and FAB-MS/MS techniques. Their structures were character

Structural analysis of non-volatile compounds by liquid chromatography/mass spectrometry and liquid chromatography/tandem mass spectrometry: thermal isomerization of benzylpenicillin in a Plasmaspray interface
Autor: Yasuko Ohki, Hidemi Nagaki, Takemichi Nakamura, Takeshi Kinoshita
Publikováno v: Biological mass spectrometry. 21(3)
Isomerization and degradation of benzylpenicillin ((2S,5R,6R)-3,3-dimethyl-7-oxo-6-(2-phenylacetamido)-4-thia-1- azabicyclo[3.2.0]heptane-2-carboxylic acid) were studied using a combination of Plasmaspray (PSP) liquid chromatography/tandem mass spect

Autor: Masaaki Kurabayashi, Tanetoshi Koyama, Takeshi Kinoshita, Masahiro Kitaoka, Kyozo Ogura, Hidemi Nagaki
Publikováno v: Analytical biochemistry. 185(1)
Applicability of negative ion fast atom bombardment (FAB)-tandem mass spectrometry (MS/MS) was examined in trace mixture analyses and structural assignments of some isoprenoid diphosphates. Negative ion FAB-MS spectra using a glycerol matrix of these
