A histidine-mediated, pendulum-like proton transport mechanism is required for the high catalytic activity of -hydrogenases

Jifu Duan, Yang Zhaoya, Oliver Lampret…·Thomas Happe

This study identifies a histidine-mediated pendulum mechanism in [FeFe]-hydrogenases that enhances catalytic activity by facilitating proton transfer.

Direct Binding of Cysteine-367 Thiolate to the Active Site of the -Hydrogenase from Clostridium beijerinckii in the O2-stable State

Jifu Duan, Federica Arrigoni, Andreas Rutz…·Thomas Happe

The paper presents a high-resolution crystal structure of CbA5H in the O2-stable Hinact state, showing direct thiol binding to the active site iron, supported by DFT calculations.
