The team gathers complementary expertise ranging from protein expression and purification to biochemical, structural and functional characterization. There is extensive experience in X-ray Crystallography, NMR, EPR, Moessbauer, Glycan Microarrays, Fast Kinetics, (Bio)Electrochemistry among other biophysical techniques. The group has access to all necessary infrastructures for Structural Biology either in-house or within the scope of National or International Networks (PT NMR Network, ESRF and other SR labs (X-ray and SAXS)).
Researchers of the SMB Group have a long-standing interest in a variety of topics that can be grouped in two broad areas: environment impact and health & disease.
In several joint projects, the different methodologies available provide a complementary Systems Biology view and characterization of different biomolecular research topics: Protein structures, spectroscopic, biophysical and biochemical characterization; Enzyme structures and catalytic mechanisms; Structural and functional analysis of protein-protein, protein-ligand and protein-glycan interactions. These topics range from bioremediation and oxidative stress to drug action and design and are of central importance for a successful achievement of the strategic goals defined for all four Thematic Lines.
