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... |

Manipulation of activity and orientation of membrane-reconstituted di-tripeptide transport protein DtpT of Lactococcus lactis.
Mol. Membr. Biol. 16(4) , 297-304, (1999) The di-tripeptide transport system (DtpT) of Lactococcus lactis was purified to apparent homogeneity by pre-extraction of crude membrane vesicles with octaethylene glycol monodecyl ether (C10E8), followed by solubilization with n-dodecyl-beta-D-maltoside (DDM... |

The inhibitory effects of cephalosporin and dipeptide on ceftibuten uptake by human and rat intestinal brush-border membrane vesicles.
J. Pharm. Pharmacol. 46(8) , 680-4, (1994) The types of inhibitory effects caused by compound V (an analogue of ceftibuten) and alanylproline (dipeptide) on the uptake of ceftibuten by brush-border membrane vesicles (BBMV) prepared from human and rat small intestine were analysed. In the presence of a... |

Conformational preferences of X-Pro sequences: Ala-Pro and Aib-Pro motifs.
J. Phys. Chem. B 114(44) , 14077-86, (2010) Conformational preferences and prolyl cis-trans isomerizations of the X-Pro motifs (Ac-X-Pro-NHMe, X = Ala and Aib) are explored using the meta-hybrid functional M06-2X and the double-hybrid functional B2PLYP-D with empirical dispersion corrections in the gas... |

Species-specific differences in the Pro-Ala rich region of cardiac myosin binding protein-C.
J. Muscle Res. Cell Motil. 30(7-8) , 303-6, (2009) Cardiac myosin binding protein-C (cMyBP-C) is an accessory protein found in the A-bands of vertebrate sarcomeres and mutations in the cMyBP-C gene are a leading cause of familial hypertrophic cardiomyopathy. The regulatory functions of cMyBP-C have been attri... |
