Default NMR studies of three-dimensional structure and positioning of CPPs in membrane model systems.

NMR studies of three-dimensional structure and positioning of CPPs in membrane model systems.

NMR studies of three-dimensional structure and positioning of CPPs in membrane model systems.

Methods Mol Biol. 2011;683:57-67

Authors: Mäler L, Gräslund A

CPPs are generally short cationic peptides that have the capability to interact directly with membranes. Most CPPs attain a three-dimensional structure when interacting with bilayers, while they are more or less unstructured in aqueous solution. To understand the relationship between structure and the effect that CPPs have on membranes, it is of great importance to investigate CPPs with atomic resolution in a suitable membrane model. Nuclear magnetic resonance (NMR) is an excellent technique both for studying solution structures of peptides as well as for investigating their location within a model bilayer. This chapter outlines protocols for producing model membrane systems for NMR investigations as well as the basic NMR tools for determining the three-dimensional structure of CPPs and for investigating the details in lipid-peptide interactions, i.e., the localization of the CPP in the bilayer.

J Magn Reson. 2011 Jul 21; Authors: Liu Y, Prestegard JH Most multi-dimensional solution NMR experiments connect one dimension to another using coherence transfer steps that involve evolution under scalar couplings. While experiments of this type have been a boon to biomolecular NMR the need to work on ever larger systems pushes the limits of these procedures. Spin relaxation...

1H NMR-based metabolic profiling reveals inherent biological variation in yeast and nematode model systems Abstract The application of metabolomics to human and animal model systems is poised to provide great insight into our understanding of disease etiology and the metabolic changes that are associated with these conditions. However, metabolomic studies have also revealed that there is significant, inherent biological variation in human samples and even in samples from animal model systems where the animals are housed under carefully controlled conditions. This inherent biological...
