Pre-Steady-State Kinetics of Catalytic Intermediates of an [FeFe]-Hydrogenase

, 2017
[FeFe]-hydrogenases catalyze the reversible production of hydrogen gas from protons and electrons, but the mechanism of catalysis is still the subject of debate.

Electrochemical control of [FeFe]-hydrogenase single crystals reveals complex redox populations at the catalytic site

, 2021
Elucidating the distribution of intermediates at the active site of redox metalloenzymes is vital to understanding their highly efficient catalysis. Here we demonstrate that it is possible to generate, and detect, the key catalytic redox states of an ...

Author Correction: Hydrogen-based metabolism as an ancestral trait in lineages sibling to the Cyanobacteria

Nature Communications, 2019
The original version of this Article contained errors in Fig. 4. In panel a, the labels ‘F420-reducing NiFe hydrogenase (group 3a)’ and ‘Group 2 NiFe hydrogenase’ were misplaced.

Metagenomics Meets Electrochemistry: Utilizing the Huge Catalytic Potential From the Uncultured Microbial Majority for Energy-Storage

Frontiers in Bioengineering and Biotechnology, 2020
Hydrogen can in the future serve as an advantageous carrier of renewable energy if its production via water electrolysis and utilization in fuel cells are realized with high energy efficiency and non-precious electrocatalysts.

A Personal Perspective on Metalloprotein Structure and the Future of Macromolecular X‐Ray Crystallography

Journal of the Chinese Chemical Society, EarlyView.
While X‐ray crystallography has been the primary method for determining the structures of metalloproteins, cryoEM has taken over this role, illustrated by [4Fe4S]‐cluster containing proteins deposited in the Protein Data Bank. What will be the role for X‐ray crystallography as cryoEM and machine learning methods dominate the initial structural analysis?

O2 reduction and O2-induced damage at the active site of FeFe hydrogenase

Nature Chemistry, 2016
FeFe hydrogenases are the most efficient H2 producing enzymes, but inactivation by O2 is an obstacle to using them in biotechnological devices. Here we combine electrochemistry, site-directed mutagenesis, molecular dynamics and quantum chemical ...

Hydride state accumulation in native [FeFe]-hydrogenase with the physiological reductant H2 supports its catalytic relevance

, 2022
Small molecules in solution may affect the stability of catalytic states and produce off-cycle states that can be mistaken for catalytically relevant species.

Outer‐Sphere Tuning of Synthetic Iron–Sulfur Clusters Within Nanoscale Cage Frameworks

Small, EarlyView.
Noncovalent encapsulation of a synthetic iron–sulfur cluster within hydrophobic, naphthalenediimide (NDI)‐paneled cages is shown to lead to dramatic changes in the electronic structure and covalency of the Fe─S core. ABSTRACT As atomic‐scale archetypes for multi‐electron transfer, iron–sulfur clusters are compelling candidates for the design of redox ...
