Effects of chemical modification of lysine residues in trypsin

Autor: Sibylla Grahn, Dirk Ullmann, Sebastian H.J. Bauer, Torsten Kurth, Christian Elsner, Hans-Dieter Jakubke

Publikováno v: Journal of Molecular Catalysis B: Enzymatic. 8:193-200

Chemical modifications are a simple method to identify and modify functional determinants of enzymes. In the case of serine proteases, it is possible to induce characteristics which are advantageous for peptide synthesis. In this work, we investigate

Mass spectrometric identification of phosphorylated vasostatin II, a chromogranin A-derived protein fragment (1–113)

Autor: Sebastian H.J. Bauer, W. Van Dongen, X. Y. Zhang, L. Dillen, F. Liang, W.P. De Potter, E. L. Esmans, Magda Claeys, Michael Przybylski

Publikováno v: Biochimica et biophysica acta : P : protein structure and molecular enzymology

Vasostatin II, an N-terminal chromogranin A-derived protein (CGA(1-113)), was purified from bovine chromaffin granule lysate and characterized by electrospray mass spectrometry (ES/MS) as being partially phosphorylated. The phosphorylation site was d

Isolation and identification of the plasma membrane-associated intracellular protein reggie-2 from goldfish brain by chromatography and Fourier-transform ion cyclotron resonance mass spectrometry

Autor: Michael Przybylski, Sebastian H.J. Bauer, Claudia A. O. Stuermer, Marianne Wiechers, Kai Bruns

Publikováno v: Analytical biochemistry. 298(1)

The neuronal protein reggie-2 is localized at the cytoplasmic face of the plasma membrane and participates, together with reggie-1, in the formation of plasma membrane microdomains. Reggie-2 exhibits several potential phosphorylation sites but whethe

Chromogranin A from bovine adrenal medulla: molecular characterisation of glycosylations, phosphorylations, and sequence heterogeneities by mass spectrometry

Autor: Sebastian H.J. Bauer, Michael Przybylski, Magda Claeys, Walter Van Dongen, Xin Yi Zhang

Publikováno v: Analytical biochemistry

Chromogranin A (CGA) is a member of a family of acidic glycoproteins present in endocrine and neuroendocrine tissues. One of its suggested physiological roles is being a precursor molecule for several peptide hormons. Further interest in this protein

Characterization of Tertiary Structure States and Specific Noncovalent Complexes of Proteins by UV-Matrix-Assisted Laser-Desorption / Ionization Mass Spectrometry

Autor: M. R. Jetschke, Michael Przybylski, Sebastian H.J. Bauer, Michael O. Glocker

Publikováno v: New Methods for the Study of Biomolecular Complexes ISBN: 9789048150175

Hydrogen/deuterium exchange reactions (H/D exchange) in solution have been used for probing protein structures and dynamics and have been monitored using a broad spectrum of analytical methods including mass spectrometry. In order to study the effect

Isolation and identification of intact chromogranin A and two N-terminal processing products, vasostatin I and II, from bovine adrenal medulla chromaffin granules by chromatographic and mass spectrometric methods

Autor: F. Liang, Magda Claeys, Michael Przybylski, X. Y. Zhang, Sebastian H.J. Bauer, W.P. De Potter

Publikováno v: Neuropeptides

Chromogranin A (CGA) is the most abundant protein of the bovine adrenal medulla and plays an important role as precursor protein of several peptides that act as modulators for endocrine cell secretory activity. Furthermore, it is presumed to play a r

Characterization of specific noncovalent protein complexes by UV matrix-assisted laser desorption ionization mass spectrometry

Autor: Michael Przybylski, Michael O. Glocker, Jürgen Volz, Jürgen Kast, Sebastian H.J. Bauer

Publikováno v: Journal of mass spectrometry : JMS. 31(11)

While electrospray (ESI) mass spectrometry has already established its potential for the characterization of non-covalent protein complexes, matrix-assisted laser desorption/ionization mass spectrometry (MALDI/MS) seemed not to be applicable hitherto
