Zakres usług i badań

Our facility provides services for the nuclear magnetic resonance (NMR) spectroscopy of biomolecules (peptides, proteins, RNA, DNA). One-dimensional and multidimensional NMR experiments on 1H, 19F, 15N, 13C, and 31P nuclei can be performed. Variable temperatures that meet most requirements of biological studies are available.

Opis usług

Our facility has expertise in the structural analysis of biomolecules in solution based on two- and three-dimensional homo- and heteronuclear spectra. Our experience includes experimental data for resonance assignments and information about molecular dynamic processes retrieved from 15N relaxation experiments. We use several techniques to extract information about binding small substrates to large proteins, which can be applicable to select inhibitors of the proteins of interest. Such techniques are indispensable in structural studies of proteins, oligonucleotides, oligosaccharides, and their complexes.


The facility is equipped with two three-channel Varian NMR spectrometers working at a magnetic field strength of 9.4 and 11.7 T, corresponding to 400 and 500 MHz 1H resonance frequencies, respectively. Standard one-dimensional spectra of 1H and nuclei from a broad-frequency range (lower limit: 40.5 MHz for 15N; upper limit: 161.9 MHz for 31P) can be recorded. Triple probe heads allow the measurement of two- and three-dimensional homo- and heteronuclear spectra. Measurements can be performed at temperatures of 0-70°C.

Opis badań

The main scientific interests of our facility focus on structural analysis and molecular dynamic processes on a protein backbone based on 15N relaxation measurements. The NMR spectrometers in the facility acquire experimental data for uniformly labeled (15N- or 13C15N-) proteins with a molecular mass up to 20 kDa. The facility has expertise with the evaluation of high-resolution three-dimensional structures of small proteins, posttranslational modifications, analysis of interaction peptides, or ligands with proteins. We are interested in exploring molecular dynamic processes based on 15N relaxation experiments. Our research projects also include studies of the trans-membrane fragments in different types of micelles or phospholipids with application diffusion measurements on 31P and 2H isotopes. We utilize NMR techniques to create effective inhibitors against selected proteins. We recently began structural analyses of proteins and peptides with paramagnetic ions, such as Cu(II), with NMR techniques based on the effects of paramagnetic relaxation enhance (PRE).
