bioRxiv 2023

This fantastic aldehyde oxidoreductase does not only oxydize a high spectrum of aldehydes or performs the thermodinamically difficult opposite reaction, but it also forms filaments in a similar fashion as the previously reported HDCR.

Molecular Basis of the Electron Bifurcation Mechanism in the [FeFe]-Hydrogenase Complex HydABC

JACS 2023

In acetogens, the electron bifurcating hydrogenase generates low potential ferredoxin for respiration and CO2 fixation in a way that differs from classical flavin-based electron-bifurcating enzymes (FBEB). After a tremendous effort with our  collaborators, we validated this novel mechanism by redox-controlled cryoEM reconstructions, molecular simulations and spectroscopy experiments.

Electron highway for hydrogen and carbon dioxide storage discovered

Together with researchers from Frankfurt and Basel, we have shed light on the structure of an enzyme that produces formic acid from molecular hydrogen (H2) and carbon dioxide (CO2). The filamentous structure of the enzyme, now described at atomic level for the first time, acts like a nanowire and is evidently responsible for the extremely efficient conversion rates of the two gases. There is no other enzyme reported that converts CO2 to formate with a turnover rate even close to HDCR.

Structure-based electron-confurcation mechanism of the Ldh-EtfAB complex

The first electron-confurcating reaction structurally studied

 

A high-resolution cryoEM structure of the lactate dehydrogenase-electron transferring flavoprotein complex (Ldh-EtfAB) from an acetogen was obtained. On this basis, a catalytic mechanism of the flavin-based electron confurcation (FBEC) process has been proposed.

The molecular machine that forms the membranes of life!​

In an amazing 6-lab cooperation we managed to determine the structure and mechanism of the major thylakoid membrane biogenesis factor VIPP1. Our work shows how this green ESCRT-III oligomer mediates membrane remodelling and repair

How to build a molecular water splitting machine?

The first structural information on the biogenesis of PSII. We trapped the attachment of the CP43 light harvesting module and determined the high-resolution structure of it. Our work answers how a not yet fully assembled, but already partially active molecular machine is protected from photo damage. Great cooperation with our friends in the Nowaczyk lab. Our future work on this topic is supported by the Walter Benz foundation.
