- By exploring the role of amino acids and the maturation enzyme HydF, new insights are being gained into the biosynthesis of the cofactor essential for hydrogen turnover.
- The study, published in the Journal of the American Chemical Society, sheds light on the biological assembly and coordination of the diiron site in [FeFe]-hydrogenases.
A research team at Ruhr University Bochum, led by Professor Thomas Happe and Rieke Haas, delved into the catalytic center of algae to unravel the mechanisms behind efficient hydrogen production. Iron-sulphur clusters in algae, particularly in [FeFe] hydrogenases, were discovered to have a unique role in facilitating the production of hydrogen, a promising green energy carrier. The team focused on the enzyme HydF, which is crucial in the final assembly steps of the cofactor necessary for hydrogen turnover. Through site-specific mutagenesis and various analytical techniques, such as hydrogen production measurements and ATR-FTIR spectroscopy, the researchers identified the significance of individual amino acids and the role of HydF in synthesizing essential ligands. This study, published in the Journal of the American Chemical Society, highlights the importance of understanding the complex biosynthesis process of [FeFe]-hydrogenases to pave the way for innovative energy production solutions.
