We are interested in understanding the biogenesis of the archaeal cell envelope including processes like N-glycosylation, the assembly of macromolecular structures like pili and the archaellum, and regulatory processes depending on protein phosphorylation. We study these processes in two model archaea: the thermoacidophilic crenarchaeon Sulfolobus acidocaldarius and the extremely halophilic euryarchaeon Haloferax volcanii.

 

We use genetic approaches to identify systems in Sulfolobus and Haloferax that are involved in the assembly of cell surface appendages and biochemically characterize the subunits and their interplay in the assembly process.

 

Our group is located at the Institute of Biology at the University of Freiburg in Southern Germany.
