Project acronym SLONMR
Project title Use of NMR Spectroscopy in
Combination with Computational Methods on Systems
of Biological Interest
Slovenian NMR Centre _at_ NIC (www.nmr.ki.si)
Basic info NMR centre offers the necessary
infrastructure and service for collection and
processing of NMR spectra to all institutions and
companies that use NMR in their research and
development as part of basic or application
research projects. 600 MHz NMR spectrometer is
used in the studies of three-dimensional
structure and dynamics of complex systems with
the high molecular mass such as proteins and
nucleic acids. The two 300 MHz instruments are
used by synthetic organic chemists, for
solid-state measurements and wine analyses as
well as for routine analyses in pharmaceutical,
chemical, food and other industries.
  • Research
  • NMR centre cooperates with many groups and
    laboratories on over 46 basic and applied
    projects in year 2001 (list available at
    http//www.nmr.ki.si/research)
  • 57 publications in international journals in 2000

Research activities (http//www.nmr.ki.si/research
) Current research projects at NMR centre
involve
  • Interactions of metal ions with nucleic acids and
    the development of new NMR techniques for the
    localization of cation binding of a variety of
    non-B-form DNA secondary structures, including
    those which contain G-quartets
  • Structure and dynamics of proteins,
  • Structural characterization of protein/peptide -
    ligand interactions,
  • Interaction of antibiotics with the cell membrane
    of bacteria,
  • Determination of very low concentrations of
    various residues in drugs,
  • Structure and purity of polymer materials, as
    well as characterization of side products in
    polymerisation reactions,
  • Structure and interactions in solid state
    materials such as zeolites,
  • Screening of the binding affinities to a target
    protein via SAR by NMR approach using either
    synthetic combinatorial libraries or libraries
    from the plant materials,
  • Development of methods of molecular modelling
    relevant for computational support of NMR
    spectroscopy. 

An important task of NMR centre is its role in
education, offering help at collection and
interpretation of NMR data to students from B.Sc.
to Ph.D. level. Equipment Varian NMR
spectrometers 600 MHz Unity Inova, 300 MHz Unity
plus, 300 MHz Unity Inova with the broad
selection of probes, workstations Sun Ultra 60
and Sun Ultra 1-140.

Objectives
Proposal promotes collaboration of our NMR centre
with groups around Europe by facilitating
exchange visits of graduate students and
post-docs as well as senior scientists which were
limited up till now due to the absence of
appropriate funding. We have close contacts with
colleagues in several fellow NMR facilities
around Europe (Uppsala-Sweden, Poznan-Poland,
Graz-Austria, Munich-Germany, Leuven-Belgium,
Montpellier-France, Sheffield-UK, Athens-Greece,
Budapest-Hungary). Our research objectives cover
the following broad areas where NMR spectroscopy
can be used as a method of choice
  1. Characterization of conformationaly restricted
    nucleosides (WP1),
  2. Development of new methodology to study
    metabolism of carbohydrates with deuterium NMR
    spectroscopy (WP2),
  3. Complex enzymatic reactions (WP3),
  4. Nucleic acid structure and conformation (WP4),
  5. Characterization of metastable states and
    conformational transitions of proteins involved
    in disease (WP6),
  6. Theoretical and experimental studies of
    intramolecular hydrogen bonding (WP8),
  7. Conformational analysis of peptidomimetic drugs
    (WP9),
  8. Interactions of glycopeptide antibiotics by
    membrane bilayers (WP10),
  9. Structural characterization of natural products
    like terpenoids and flavonoids (WP11).

Experiences Comments
  • Centre of Excellence plays a very positive role
    in promoting collaborations of our NMR centre
    with groups around Europe.
  • Status of EU Centre of Excellence has
    strengthened the position of NMR centre in
    Slovenia.
  • Frustrations in contacts with huge bureaucratic
    apparatus.
  • Delays in response from administration.
  • Very difficult to get clear answer on a specific
    question during preparation (problems with even
    two types of proposal forms) and realisation
    phases (e.g. how to prepare cost statements).
  • Greater mobility is a nice idea, but will
    probably take some more time to make it a
    reality.
  • Hopes for future investment from EC in research
    equipment of Slovenian NMR center. New higher
    field NMR spectrometer would serve a role of
    regional infrastructure and facility in Central
    and East Europe.
  • Overall experience is very positive and clearly
    stimulating.
