alpha and beta Conformational preferences in fibril forming peptides characterised using NMR and CD techniques
(Ios PressAmsterdamHolanda, 2004)
Unblocked statistical-coil tetrapeptides and pentapeptides in aqueous solution: a theoretical study
(Springer, 2002-03)
NMR studies of the molecular conformations of peptides and proteins rely on a comparison of the relevant spectral parameters with the corresponding values for so-called statistical-coilpolypeptides. For this reason, it is ...
Pressure dependence of side chain 13C chemical shifts in model peptides Ac-Gly-Gly-Xxx-Ala-NH2
(2017-10-01)
For evaluating the pressure responses of folded as well as intrinsically unfolded proteins detectable by NMR spectroscopy the availability of data from well-defined model systems is indispensable. In this work we report ...
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 ...
Interaction of cyclic and linear labaditin peptides with anionic and zwitterionic micelles
(2014)
Conformational changes of the cyclic (Lo) peptide Labaditin (VWTVWGTIAG) and its linear analogue (L1) promoted by presence of anionic sodium dodecyl sulfate (SDS) and zwitterionic L-α-Lysophosphatidylcholine (LPC) micelles ...
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 ...
Molecular interactions of an ornithine-rich pH-responsive self-Assembling peptide with a model lipid membrane: Conformational aspects
(2016-09-01)
Investigating interactions of designed peptide-based biomaterials with lipid membranes is important for applications in nanobiotechnology. Here the interaction of an ornithine-rich pH-responsive peptide called P11-5 with ...
Molecular dynamics simulations of signal sequences at a membrane/water interface
(1995)
A recently developed software has been used to model peptides at a cytoplasdmembrane mimetic environment where the interface is represented by a discontinuity in the dielectric constant. Molecular dynamics and
energy ...
Interaction of cyclic and linear Labaditin peptides with anionic and zwitterionic micelles
(Elsevier B.V., 2015-01-15)
Conformational changes of the cyclic (Lo) peptide Labaditin (VWTVWGTIAG) and its linear analogue (L-1) promoted by presence of anionic sodium dodecyl sulfate (SDS) and zwitterionic L-alpha-Lysophosphatidylcholine (LPC) ...
How C-terminal carboxyamidation alters the biological activity of peptides from the venom of the eumenine solitary wasp
(Amer Chemical Soc, 2004-05-18)
Inflammatory peptides display different types of post-transcriptional modifications, such as C-terminal amidation, that alter their biological activity. Here we describe the structural and molecular dynamics features of ...
