Site-selective Protonation of the Catalytic Cofactor in [FeFe]-Hydrogenase

open access: yes, 2019
Hydrogenases are microbial redox enzymes that catalyze H2 oxidation and proton reduction (H2 evolution). While all hydrogenases show high H2 oxidation activities, [FeFe]-hydrogenases are excellent H2 evolution catalysts as well.

Computational study of electron transport in [FeFe] hydrogenase enzymes

open access: yes, 2021
[FeFe] hydrogenase enzymes can reversibly catalyze the conversion of protons into molecular hydrogen. The active site of the [FeFe] hydrogenase enzyme is buried inside the protein.

Electroenzymatic CO2 Fixation

open access: yesAngewandte Chemie International Edition, EarlyView.
Electroenzymatic CO2 fixation enables energy‐efficient, highly selective synthesis of complex molecules. Unlocking its full potential requires fundamental understanding of electrode‐coupled reductases and carboxylases. This review critically discusses available enzymes, product scope, and key thermodynamic and kinetic considerations, highlighting ...

Hydrogen Metabolism in Helicobacter pylori Plays a Role in Gastric Carcinogenesis through Facilitating CagA Translocation

open access: yesmBio, 2016
A known virulence factor of Helicobacter pylori that augments gastric cancer risk is the CagA cytotoxin. A carcinogenic derivative strain, 7.13, that has a greater ability to translocate CagA exhibits much higher hydrogenase activity than its parent ...
