New materials for bio-based hydrogen synthesis



Synthetic biology enables spontaneous protein activation

“Nature Chemical Biology”: Design and production of hydrogenases simplified significantly

Researchers at the Ruhr-Universität Bochum (RUB) have discovered an efficient process for hydrogen biocatalysis. They developed semi-synthetic hydrogenases, hydrogen-generating enzymes, by adding the protein's biological precursor to a chemically synthesized inactive iron complex. From these two components, the biological catalyst formed spontaneously in a test tube. “Extracting hydrogenases from living cells is highly difficult,” says Prof Dr Thomas Happe, head of the work group Photobiotechnology at the RUB. “Therefore, their industrial application has always been a long way off. Now, we have made a decisive step towards the generation of bio-based materials.” Together with colleagues from the MPI Mülheim and from Grenoble, the RUB researchers report their findings in the journal “Nature Chemical Biology”.
