Research
My research focuses on the isolation and characterization of the membrane-bound organohalide respiration complex (OHR) from Dehalococcoides mccartyi strain CBDB1 that is well known for its ability to reductively dehalogenate many chlorinated and brominated organohalides. We try to get deeper insights into the organization of the OHR complex by applying different biochemical methods like solubilization of the OHR complex with detergents, enrichment with size-exclusion chromatography or blue native-PAGE, heterologous production coupled to mass spectrometry.
Additionaly, we are interested in metabolic processes that are strongly conserved in microorganisms with ancient traits like Dehalococcoidia. By identifying, purifying and characterizing proteins involved in these processes, we can shed light in early evolution of proteins and life.
