Description of Research

Protein-ligand interactions mapped by NMR

The Group is interested in the principles of communicaton and cooperation in biology that we study with the tools of bioinformatics, structural biology and protein chemistry. Both the structural organization and the molecular interactions of proteins can be described as specific and robust networks. A better knowledge of the macromolecular stability and specificity is important for practical purposes such as understanding the cellular mechanisms or the design of better pharmacons. The lab uses the approaches of bioinformatics, peptide chemistry, NMR, mass spectrometry and recombinant DNA technologies. It studies the proteins of the Notch signalling network and its involvement in genetic diseases. In particular, it looks at the formation of disulfide bonds in proteins; evolution of network stability and systems biology; prediction of protein structure and function using machine learning approaches, and aspects of protein chemistry including synthesis of modified peptides and pharmaceutical applications.

Our current bioinformatics topics include the development of computational tools for manycore computer architectures, novel search techniques for proteomics and computational modelling of bacterial communications. More
