Protein Engineering & Dynamics
How does nature succeed in creating our diverse protein world of complex architectures and sophisticated molecular machines from just linear chains of amino acids? We are seeking to find answers to this question…
The linear chains of amino acids are called proteins and act as folded structures or intrinsically disordered entities that carry out critical functions in virtually all aspects of life. Protein functional diversity ranges from macroscopic material over molecular motility to biochemical catalysis and signalling. Functional diversity is rooted in the astronomical number of possible sequences that the cellular protein synthesis machinery can generate using only 20 different amino acids as building blocks. Evolution selects for function a tiny subset from this tremendous pool of sequences, which transforms into uniquely folded structural entities or remains intrinsically disordered. Structural studies deliver an ever-increasing number of atomic-detailed snapshots of proteins deposited in the Protein Data Bank, which provide our current basis for understanding protein function at a molecular level. But recent years witnessed increasing appreciation that dynamic disorder and conformational change are integral part of function. Often, function is the result of specific structural changes that are triggered or modulated by external stimuli. Deciphering protein mechanisms thus requires the observation of conformational change. This task represents a major challenge for current molecular biology and biophysics because spectroscopy that can detect it is rare.
We investigate proteins that are key players in human biology and disease or that are implicated in material science. We apply protein engineering to introduce high-resolution fluorescence probes that uncover conformational motion and to investigate the contribution of individual amino acids to folding and function. We combine modern methods of molecular biology, including recombinant DNA technology, site-directed mutagenesis and heterologous protein expression, with state-of-the-art fluorescence and complementary protein spectroscopy, involving single-molecule methods and kinetics in multidisciplinary approaches.
