The electronic and molecular structures of protein nanotubes (PNT’s) have been investigated theoretically by first-principles electronic structure calculations. The results have been discussed in comparison to those of the polypeptide open chains (POC’s) and polypeptide closed rings (PCR’s) in order to give a systematic understanding. Focusing on the intra-ring and inter-ring hydrogen bonds (HB’s), we also investigate the PCR stacking mechanism. The present calculation reveals that PNT’s are semiconductors and that an extra proton in the tube interior has the potential to be an electron acceptor.
