For the realization of a practical high-throughput protein detection and analysis system, a novel peptide array has been constructed using a designed glycopeptide model library with an α-helical secondary structure. This study will contribute the increment of the diversity of such an array system and the application to focused proteomics and ligand screening by effective detection of sugar-binding proteins. Fluorescent glycopeptides with an α-helix, a β-strand, or a loop structure were designed initially to select a suitable scaffold for the detection of a model protein. After selection of the α-helical structure as the best scaffold, a small model library with various saccharides was constructed to have charge and hydrophobicity variations in the peptide sequences. When various sugar-binding proteins were added to the peptide library array, the fluorescent peptides showed different responses in fluorescence intensities depending on their sequences as well as saccharides. The patterns of these responses could be regarded as "protein fingerprints" (PFPs), which are able to establish the identities of the target proteins. The resulting PFPs reflected the recognition properties of the proteins. Furthermore, statistical data analysis from obtained PFPs was performed using a cluster analysis. The PFPs of sugar-binding proteins were clustered successfully depending on their families and binding properties. These studies demonstrate that arrays with glycopeptide libraries based on designed structures can be promising tools to detect and analyze the target proteins. Designed peptides with functional groups such as sugars will play roles as the capturing agents of high-throughput protein nano/micro arrays for focused proteomics and ligand screening studies.

We synthesized the peptide nanorings of cyclo[-(D-Ala-L-Gln)(3)], cyclo[-(D-CyS-L-Gln)(3)], CyC10[-D-Cys-L-HiS-D-Ala-L-Asn-Gly-L-Gln-1 and Cyc1o[-(L-Gln)(5)], and studied the way in which the difference in the type and/or number of component amino acid residues changes the self-assembling morphology of the nanorings on gold substrates by atomic force microscopy. The study revealed that CyClo[-(D-Ala-L-Gln)(3)] formed nanotube bundles through inter-ring hydrogen bonds, while the nanorings of CyC10[-(D-CyS-L-Gln)3] adhered to the gold surface directly due to the high affinity of thiol to gold. In contrast, a random amino acid sequence of cyclo[-D-CyS-L-HiS-D-Ala-L-Asn-GlY-L-Gln-] resulted in many isolated nanotubes, which were first observed in the present study. While the D,L-peptide nanotubes have very straight forms, the homo-L-peptide of cyclo[-(L-Gln)(5)] formed interesting randomly branching nanotubes that were entwined and grew on the substrate. Scanning tunneling microscopy was also performed and high-resolution images of both the peptide nanotubes and the nanotube bundles were obtained.

We here report our theoretical as well as experimental studies on the stacking manner of peptide nanorings (PNRs) in peptide nanotubes (PNTs). We focus on the molecular vibrations of N-H and C=O stretching modes and discuss this subject via their infrared (IR) spectroscopy, because PNTs are formed by the inter-ring H bonds between the adjacent PNRs via -N-H(...)O=C-. Symmetry analysis based on group theory reveals that parallel stacking causes two IR active modes in these molecular vibrations while three modes are active in the antiparallel stacking. This difference in the number of IR active modes is determined only by the stacking manner and not by the number of amino acid residues composing the PNRs. By using two typical PNRs Of cyclo[-((L)-Gln-D-Ala)(3)] and cyclo[-((L)-Gln-(D)-Ala)(4)], we further studied the favorable stacking manners of PNRs via IR observation. Our IR experiments as well as the ab initio energetics show that the former PNRs create a PNT by stacking themselves in parallel while the latter PNRs do so by stacking themselves in an antiparallel manner.
