Hydrogen synthesis: When enzymes assemble themselves in the test tube

Researchers have engineered a hydrogen-producing enzyme in the test tube that works as efficiently as the original. The protein – a so-called hydrogenase from green algae – is made up of a protein scaffold and a cofactor. The latter is the reaction center where the substances that react with each other dock. When the researchers added various chemically synthesized substances to the protein scaffold, the cofactor spontaneously assembled.
