Aggregation of capped hexaglycine strands into hydrogen-bonding motifs representative of pleated and rippled β-sheets, collagen, and polyglycine I and II crystal structures. A density functional theory study.
J. Phys. Chem. B 115 , 1562-1570, (2011) We compare the energies and enthalpies of inter-action of three- and seven-stranded capped polyglycine aggregates in both the pleated and rippled antiparallel and parallel β-sheet structures as well as the collagenic (three-strand) or polyglycine II-like (sev... |

Catalytic oxidation of uric acid at the polyglycine chemically modified electrode and its trace determination.
Analyst 122 , 839-841, (1997) Cyclic voltammetry was undertaken to investigate the electrochemical behavior of uric acid at a polyglycine modified electrode. The modified electrode shows catalytic ability for the oxidation of uric acid, reducing the overpotential by 250 mV in pH 7.0 phosp... |

One-pot electrosynthesis of polyglycine-like thin film on platinum electrodes as transducer for solid state pH measurements.
Talanta 82 , 417-421, (2010) The anodic oxidation of concentrated glycine based aqueous electrolyte on smooth platinum electrode leads to a strongly grafted polyglycine-like coating on the surface in an irreversible way. Due to the proton affinity towards amino groups of polyglycine (PG)... |

Communications: Is quantum chemical treatment of biopolymers accurate? Intramolecular basis set superposition error (BSSE).
J. Chem. Phys. 132(23) , 231101, (2010) The accuracy of quantum chemical treatment of biopolymers by means of density functional theory is brought into question in terms of intramolecular basis set superposition error (BSSE). Secondary structure forms--beta-strands (C5; fully extended conformation)... |

Structure of sodiated octa-glycine: IRMPD spectroscopy and molecular modeling.
J. Am. Soc. Mass Spectrom. 21(5) , 728-38, (2010) The structure of the sodiated peptide GGGGGGGG-Na(+) or G(8)-Na(+) was investigated by infrared multiple photon dissociation (IRMPD) spectroscopy and a combination of theoretical methods. IRMPD was carried out in both the fingerprint and N-H/O-H stretching re... |
