Research Topics:
1)Elucidation of the conjugative plasmid transfer mechanisms of Gram-positive pathogenic bacteria: The mechanism seems to be related to the type IV protein secretion mechanism responsible for effector/toxin transfer from Gram-negative pathogenic bacteria to eukaryotic hosts and effective in conjugative plasmid transfer in Gram-negative bacteria. Model plasmid of our studies is the multiple antibiotic resistance plasmid pIP501 with the broadest known host range for a plasmid originating from Gram-positive bacteria known until now. A protein-protein interaction map of the transfer proteins was established and all transfer proteins are supplied to biochemical/biophysical analysis and 3D structure solution. Model organisms are Enterococcus faecalis and Streptococcus pneumoniae. 2) Protein-protein interaction studies between Enterococcus faecalis virulence proteins/surface-associated proteins with human proteins to elucidate key protein-protein interactions effective in Enterococcus pathogenesis. Identified targets are evaluated with respect to use as potential drug targets.


Organisms studied:


Special methods / technologies:
yeast two-hybrid assay, automated yeast two-hybrid screening (HT) Protein crystallography, SAXS, CD-spectroscopy


Suggestions for potential research cooperations:
3D-structural analysis of proteins involved in conjugation and protein secretion
