April 2025 - New publication
Congratulations to Giada on her new publication! We report on the rate-determining step(s) of dark-operative protochlorophyllide oxidoreductase (DPOR) under different conditions, noting that we observe cooperativity during enzyme-substrate complex formation prior to catalysis.
We welcome Andrea to the group as a PhD Researcher on [FeFe]-hydrogenases!
November 2024 - New publication
Congratulations to Sophie on her new publication! We report that the confinement of [FeFe]-hydrogenase in a mesoporous electrode structure, in comparison to a flat electrode of the same material, increases both the electrocatalytic activity and stability of the enzyme. We thank our collaborators: Astrit, Ulf-Peter and Thomas.
November 2024 - New publication
Congratulations to Daniel and Danielle for their new publication! Here, we explore protein-mediated protection of the alternative V-nitrogenase. We found that cross-coupling the Mo- and V-nitrogenases affords protein, although only in one combination.
October 2024 - Welcome to Nils and to Kilian
We welcome Nils OSTERMANN (left) and Kilian ZUCHAN (right) as postdocs in our group!
October 2024 - Welcome to Lisa
We welcome Lisa KLIMPER for a research stay during her PhD at Aarhus!
October 2024 - Welcome to Nadiia and Clémence
We welcome Nadiia VORONTSOVA (left) and Clémence DELAGE DE LUGET (right) for their MSc theses in the group!
September 2024 - Welcome to Thomas
We welcome Thomas BERLAMONT to the group as an appretice!
Congratulations to Giada for winning a prize for the "Best Life Science presentation" at the annual Geneva Chemistry and Biochemistry Days conference (held at UNIGE). Sponsored by Life Science Switzerland.
December 2023 - !! Cécile graduates !!
Congratulations to the first PhD researcher of the group, Cécile, who has now graduated with a PhD in Chemistry. Good luck in your future endeavors!
November 2023 - New publication
Congratulations to the team (in particular Cécile and Nevena (MPI Bremen)) on our recent publication, where we disrupted nitrogenase's highly conserved mononuclear metal-binding site between the two αβ halves of nitrogenase's α2β2 hetero-tetrameric MoFe protein. The 1.55 Å X-ray crystal structure confirms the loss of metal at this site. Interestingly, most of the properties of the MoFe protein remain unchanged in vitro. However, protein-mediated protection against O2 deactivation may be affected, implying longe-range conformational changes may be regulated by this MMB. More work needed!
September 2023 - New publication
Congratulations to the team (especially Semihan, BERCO2) and our collaborators on our recent publication, where we report electroenzymatic CO2 reduction to formate using the fascinating enzyme formylmethanofuran dehydrogenase. On electrode surfaces, this enzyme strongly favors the reductive reaction!
May 2023 - New publication
Congratulations to the team (especially Cécile) and our collaborators on our recent publication, where we show that both halves of nitrogenase's MoFe protein are not required for N2 fixation (in vitro).
12/01/2023 - Welcome to Stefanie Birneder
Welcome to Stefanie BIRNEDER who joins us for a bachelor internship from TUMunich.
January 2023 - Welcome to Enzo Vigny
Welcome to Enzo VIGNY, who will undertake a MSc Internship (2 months) in the group!
January 2023 - New publication
Congratulations to the team (especially Yongpeng and Sophie) on our recent publication, where we report a simple and accessible single-step electrode preparation procedure for [FeFe]-hydrogenase electrochemistry. We observed very high stability and electrocatalytic activity for H2 formation under mild conditions.
November 2022 - End of year fondue
We celebrated the end of 2022 with a nice group fondue!
June 2022 - Welcome to this summer's masters students

March 2021 - New publication
Congratulations to the team on our recent publication, where we report on techniques to follow electroenzymatically generated hydrogen (by hydrogenase). Rotating ring disk electrochemistry can efficiently detect hydrogen produced at the disk electrode. Further, online mass spectrometry is capable of simultaneously following the formation of molecular hydrogen (H2), deuterium hydride (HD) and molecular deuterium (D2), permitting the determination of kinetic isotope effects.
March 2020 - New review
Our review titled "Recent Enzymatic Electrochemistry for Reductive Reactions" has been accepted for publication in ChemElectroChem. Congratulations to Cécile!
