Journal ArticleDOI
Protein oxidation during temperature-induced amyloid aggregation of beta-lactoglobulin.
TL;DR: Different morphologies of amyloid aggregates of beta-lactoglobulin were prepared by incubation at pH 2 or pH 3.5 for up to 72 h and the building blocks at both pH values changed towards smaller peptides.
Journal ArticleDOI
Influence of the polydispersity of pH 2 and pH 3.5 beta-lactoglobulin amyloid fibril solutions on analytical methods
Timon R. Heyn,Vasil M. Garamus,Hendrikje R. Neumann,Maximilian J. Uttinger,Tobias Guckeisen,Monique Heuer,Christine Selhuber-Unkel,Wolfgang Peukert,Julia K. Keppler,Julia K. Keppler +9 more
TL;DR: In this paper, strong superposition effects were evident with common analyses such as FTIR, TRP fluorescence and Thioflavin-T. At the same time, structural differences of pH 2 and pH 3.5 aggregates could be presented more clearly.
Journal ArticleDOI
Towards recombinantly produced milk proteins: Physicochemical and emulsifying properties of engineered whey protein beta-lactoglobulin variants
Julia K. Keppler,Julia K. Keppler,Anja Heyse,Eva Scheidler,Maximilian J. Uttinger,Laura Fitzner,Uwe Jandt,Timon R. Heyn,Vanessa Lautenbach,J.I. Loch,Jonas Lohr,Helena Kieserling,Gabriele Günther,Elena Kempf,Jan Hendrik Grosch,Krzysztof Lewiński,Dieter Jahn,Christian Lübbert,Wolfgang Peukert,Ulrich Kulozik,Stephan Drusch,Rainer Krull,Karin Schwarz,Rebekka Biedendieck +23 more
TL;DR: Two recombinant beta-lactoglobulin (BLG) B variants were produced in E. coli and production/isolation resulted in native BLG without post-translational modifications, showing similar emulsifying properties to natural BLGs.
Journal ArticleDOI
The threshold of amyloid aggregation of beta-lactoglobulin: Relevant factor combinations
Timon R. Heyn,Julian K. Mayer,Hendrikje R. Neumann,Christine Selhuber-Unkel,Arno Kwade,Karin Schwarz,Julia K. Keppler,Julia K. Keppler +7 more
TL;DR: In this paper, the authors identify critical factor combinations of pH, temperature, stirring speed, protein and ion concentration that specifically affect the lag-, and growth phase of beta-lactoglobulin amyloid aggregation.
Journal ArticleDOI
Engineering amyloid and amyloid-like morphologies of β-lactoglobulin
L.J.G. Hoppenreijs,Laura Fitzner,T. Ruhmlieb,Timon R. Heyn,K. Schild,K. Schild,A.J. van der Goot,Remko M. Boom,Anja Steffen-Heins,Karin Schwarz,Julia K. Keppler,Julia K. Keppler +11 more
TL;DR: In this article, conditions under which amyloid-like aggregates are formed and their impact on aggregate morphology are identified and summarized, where the focus is on β-lactoglobulin, but generic effects on other proteins are discussed.
