The incorporation of a single beta-aminoethane sulfonyl amide moiety in a highly amyloidogenic peptide sequence resulted in a complete loss of amyloid fibril formation. Instead, supramolecular folding morphologies were observed. Subsequent chemoselective N-alkylation of the sulfonamide resulted in amphiphilic peptide-…

Endoergic electron transport across vesicle bilayers from ascorbate (Asc-) in the inner waterpool to methylviologen (MV2+) in the outer aqueous solution was driven by the irradiation of pyrene derivatives embedded in the vesicle bilayers. The initial rate of MV2+ reduction is dependent on the substituent group of the…

Current projects for the massive characterization of proteomes are generating protein sequences and, to less extent, three dimensional structures with unknown function. Experimentally determining functional features of a protein is expensive, time consuming and difficult to automate. There is therefore a demand for co…

Indole-3-acetic acid (IAA) activation by horseradish peroxidase (HRP) has been suggested as a new cancer therapy. Interestingly, we found that ultraviolet B UVB radiation also can activate IAA and produce free radicals in a dose-dependent manner. In this study, we attempted to identify the free radicals generated by U…
