Research

Vitamin B12-containing enzymes fulfill central functions in the energy conservation and cell mass production of anaerobic microbes. The phylogenetically diverse group of reductively dehalogenating bacteria utilizes cobamides (B12 vitamers) as cofactors of the key enzyme in their energy metabolism, the respiratory reductive dehalogenase. This membrane-bound iron-sulfur protein represents the terminal reductase of a respiratory chain that couples the enzymatic reductive dehalogenation of chlorinated or brominated hydrocarbons to the formation of a proton motive force (organohalide respiration).

The research group is studying the composition and functionality of the organohalide respiratory chain in reductively dehalogenating bacteria. Furthermore, the structure and function of reductive dehalogenases are investigated. Unraveling the role of the cobamide cofactor in catalysis, its acquisition and structural variability in different representatives represent a substantial part of our research. We are investigating the mechanism of sensing halogenated organic compounds that triggers the expression of genes involved in organohalide exploitation. The results of our research are going to provide molecular details of a poorly understood mode of anaerobic respiration, which is built on cobamide biochemistry.
