Properties of cyclo-β-tetrapeptide assemblies investigated by means of DFT calculations
(2006)
We present a theoretical study of structural, energetic, and electronic properties of hollow tubular structures of cyclo-β-tetrapeptides using density functional theory methods. Our calculations consider first a cyclic ...
INTRAMOLECULARLY QUENCHED FLUOROGENIC TETRAPEPTIDE SUBSTRATES for TISSUE and PLASMA KALLIKREINS
(Academic Press Inc Jnl-comp Subscriptions, 1991-02-01)
Pressure response of amide one-bond J-couplings in model peptides and proteins
(SpringerDordrecht, 2014-09)
The pressure dependence of the one-bond indirect spin-spin coupling constants 1 J N-H was studied in the protected tetrapeptides Ac-Gly-Gly-Xxx-Ala-NH2 (with Xxx being one of the 20 proteinogenic amino acids). The response ...
An antifungal tetrapeptide from the culture of Penicillium canescens
(Wiley VCH Verlag, 2009-08)
A new tetrapeptide D-Phe-L-Val-D-Val-L-Tyr (1), along with three known diketopiperazines and pseurotin A, were isolated from the culture of Penicillium canescens, collected from pollen from beehives, in a screening for new ...
Thermoanalytical study about histidine and cysteine-cadmium interactions

TETRAPEPTIDE SUBSTRATES for the DISCRIMINATION AMONG KALLIKREINS and OTHER TRYPSIN-LIKE SERINE PROTEINASES
(Walter de Gruyter & Co, 1986-03-01)
14-helical folding in a cyclobutane-containing beta-tetrapeptide
(AMER CHEMICAL SOC, 2004-07-23)
The efficient synthesis of tetrapeptide 5 containing, in alternation, cyclobutane and beta-alanine residues is described. NMR experiments both at low temperature in CDCl3 and at 298 K in DMSOd(6) solutions show the ...
Pressure Dependence of N-15 Chemical Shifts in Model Peptides Ac-Gly-Gly-X-Ala-NH2
(MDPI AGBASEL, 2012)
High pressure NMR spectroscopy has developed into an important tool for studying conformational equilibria of proteins in solution. We have studied the amide proton and nitrogen chemical shifts of the 20 canonical amino ...
14-Helical folding in a cyclobutane-containing β-tetrapeptide
(American Chemical Society, 2004-08)
The efficient synthesis of tetrapeptide 5 containing, in alternation, cyclobutane and β-alanine residues is described. NMR experiments both at low temperature in CDCl3 and at 298 K in DMSO-d6 solutions show the contribution ...
