Hydrogenases can generate hydrogen gas, but oxygen sensitivity often limits their practical applications. Investigations of an oxygen-tolerant [NiFe] hydrogenase now show that an unusual FeS cluster with six cysteine ligands alters the electron pathway to reduce unwanted oxygen and maintain enzyme function.
A unique iron-sulfur cluster is crucial for oxygen tolerance of a [NiFe]-hydrogenase
