The garlic derived compounds allicin and diallyl disulfide were bound covalently to the native and heat denatured protein. The binding site and the influence of the modification on the digestibility were determined by mass spectrometric analysis of the modified beta-lactoglobulin. Further, the conformation of the modified protein was assessed by circular dichroism and dynamic light scattering. The free thiol group of Cys(121) turned out to be the major binding site. After proteolysis with trypsin at pH 7 but not with pepsin at pH 2, a limited transfer to other cysteinyl residues was observed. The covalently bound ligands did not mask any proteolytic cleavage sites of pepsin, trypsin or chymotrypsin. The modified beta-lactoglobulin showed a native like conformation, besides a moderate loosening of protein folding. The covalent binding of organosulfur compounds to beta-lactoglobulin provides a bioactive ingredient without impairing the digestibility and functional properties of the protein.

This process leads to the formation of multinucleated giant cells and facilitates bacterial access to an uninfected host cell in a direct manner. Despite its importance in virulence, the mechanism of the T6SS-5 and the role of host cell factors in cell-cell fusion remain elusive. To date, the T6SS-5 is the only system of bacterial origin known to induce host-cell fusion. To gain insight into the nature of T6SS-5-stimulated membrane fusion, we investigated the contribution of cholesterol and proteins exposed on the host cell surface, which were shown to be critically involved in virus-mediated giant cell formation. In particular, we analyzed the effect of host cell surface protein and cholesterol depletion on the formation of multinucleated giant cells induced by B. thailandensis. Acute protease treatment of RAW264.7 macrophages during infection with B. thailandensis followed by agarose overlay assays revealed a strong reduction in the number of cell-cell fusions compared with EDTA treated cells. Similarly, proteolytic treatment of specifically infected donor cells or uninfected recipient cells significantly decreased multinucleated giant cell formation. Furthermore, modulating host cell cholesterol content by acute cholesterol depletion from cellular membranes by methyl-beta-cyclodextrin treatment or exogenous addition of cholesterol impaired the ability of B. thailandensis to induce cell-cell fusions. The requirement of physiological cholesterol levels suggests that the membrane organization or mechanical properties of the lipid bilayer influence the fusion process. Altogether, our data suggest that membrane fusion induced by B. pseudomallei and B. thailandensis involves a complex interplay between the T6SS-5 and the host cell.}, language = {en} } @misc{ZaunEtteHolletal.2019, author = {Zaun, Jill Rabea and Ette, Ottmar and Holl, Frank and Rapisarda, Cettina and Rebok, Sandra and Schwarz, Ingo}, title = {HiN : Alexander von Humboldt im Netz}, number = {37}, editor = {Ette, Ottmar and Knobloch, Eberhard}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, issn = {2568-3543}, doi = {10.25932/publishup-42824}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-428241}, pages = {117}, year = {2019}, abstract = {-Jill Rabea Zaun: Eduard Hildebrandts „Wunderbild" in einem Brief von Alexander von Humboldt an Henriette Mendelssohn, geb.
