Molecular pendulum shuttles protons to enable rapid hydrogen production in enzymes
Nearly all metabolic processes require protons—positively charged hydrogen atoms. Although these are abundant in the cellular fluid, the biocatalysts involved depend on mechanisms for efficiently capturing protons and transporting them to the site where catalysis occurs. Enzymes from microorganisms can produce hydrogen (H₂) by combining electrons with protons. These so-called hydrogenases are so…
