Here, we joined two independent biological functions in a single highly restricted peptide to support the hypothesis that the β-hairpin shape is the common basis of two otherwise unrelated biological recognition processes. To achieve this, the hydrophobic cluster HWX4LV from the decapeptide cyclic hairpin model peptide C1-C10 cyclo-CHWEGNKLVC was included in the bicyclic peptide 2. The designed β-hairpin peptide C4-C17, C8-C13 bicyclo-KHQCHWECTZGRCRLVCGRSGS (2, Z = citrulline), serves, on the one hand, as a specific epitope for rheumatoid autoantibodies and, on the other hand, shows a not negligible antibiotic effect against the bacterial strain E. coli AS19.}, language = {en} }
