Electronic Structures of Protein Nanotubes

Abstract

The electronic structures of protein nanotubes, which areformed by the periodical stacking of cyclo-peptide-rings (CPRs), aretheoretically investigated in terms of ab initiocalculations. The interring interaction is caused through theinterring H bonds, when CPRs are periodically stacked. Thisinteraction has a potential to delocalize electrons and holes towardthe tube axis, so that the band conduction occurs throughout theinterring H bonds.
