Differential mobility spectrometry of isomeric protonated dipeptides: modifier and field effects on ion mobility and stability.
Anal. Chem. 83 , 3470-3476, (2011) The ability to resolve isomeric protonated dipeptides was investigated with the new technique of differential ion mobility mass spectrometry that uses "modifier" molecules to enhance differential mobility. Two pairs of protonated peptides [glycine-alanine (Gl... |

Infrared spectroscopy of the alanine dipeptide analog in liquid water with DFT-MD. Direct evidence for P(II)/beta conformations.
Phys. Chem. Chem. Phys. 12 , 10198-10209, (2010) Following our previous work [J. Phys. Chem. B. Lett., 2009, 113, 10059], DFT-based molecular dynamics (DFTMD) simulations of 2-Ala peptide (i.e. Ac-Ala-NHMe dialanine peptide analog with methyl group caps at the extremities) immersed in liquid water at room t... |

Water-mediated conformations of the alanine dipeptide as revealed by distributed umbrella sampling simulations, quantum mechanics based calculations, and experimental data.
J. Phys. Chem. B 115 , 4880-4886, (2011) An exhaustive umbrella sampling simulation of the alanine dipeptide in solution is reported. The presence of stable Y conformations in solution is assessed by both quantum calculations and experimental data from X-ray and NMR protein-solved structures availab... |

Selectivity of quadruplex DNA stationary phases toward amino acids in homodipeptides and alanyl dipeptides.
Electrophoresis 25 , 1230-1236, (2004) Series of dipeptides, including homodipeptides and alanyl dipeptides, were separated using quadruplex (G-quartet) DNA stationary phases in open-tubular capillary electrochromatography (OTCEC). The stationary phases were constructed by covalently attaching the... |

Estimation of the pH-independent binding constants of alanylphenylalanine and leucylphenylalanine stereoisomers with beta-cyclodextrin in the presence of urea.
Electrophoresis 20(1) , 171-9, (1999) The separation of stereoisomers, particularly enantiomers, is important when their physiological activity differs. We have resolved the four stereoisomers each of alanylphenylalanine (Ala-Phe) and of leucylphenylalanine (Leu-Phe) by capillary electrophoresis ... |

Single-conformation ultraviolet and infrared spectroscopy of model synthetic foldamers: beta-peptides Ac-beta3-hPhe-beta3-hAla-NHMe and Ac-beta3-hAla-beta3-hPhe-NHMe.
J. Am. Chem. Soc. 130(14) , 4795-807, (2008) The conformational preferences and infrared and ultraviolet spectral signatures of two model beta-peptides, Ac-beta3-hPhe-beta3-hAla-NHMe (1) and Ac-beta3-hAla-beta3-hPhe-NHMe (2), have been explored under jet-cooled, isolated-molecule conditions. The mass-re... |

Simultaneous determination of Angiotensin I-converting enzyme inhibitory peptides in tryptic casein hydrolysate by high-performance liquid chromatography combined with a replicate heart-cut column-switching technique.
J. Agric. Food Chem. 55(21) , 8367-71, (2007) A replicate heart-cut column-switching HPLC method combined with two switching valves was newly developed for the simultaneous determination of three antihypertensive peptides (Ala-Phe, Tyr-Pro, and Trp-Tyr) in tryptic casein hydrolysate in one run-in assay. ... |

Computed and experimental chemical shift parameters for rigid and flexible YAF peptides in the solid state.
J. Phys. Chem. B 116(6) , 1974-83, (2012) DFT methods were employed to compute the (13)C NMR chemical shift tensor (CST) parameters for crystals of YAF peptides (Tyr-Ala-Phe) with different stereochemistry for the Ala residue. Tyr-D-Ala-Phe 1 crystallizes in the C2 space group while Tyr-L-Ala-Phe cry... |

Chiral separation based on ligand-exchange capillary electrophoresis using a copper(II)-L-ornithine ternary complex as selector.
Electrophoresis 26(4-5) , 1007-12, (2005) A ligand-exchange capillary electrophoresis was explored, with L-ornithine as the ligand and copper(II) as the central ion. Its applicability was demonstrated with underivatized and dansyl amino acids, a dipeptide, and drugs with amino alcohol structure. The ... |
