Genome-Scale Mining of Acetogens of the Genus Unveils Distinctive Traits in [FeFe]- and [NiFe]-Hydrogenase Content and Maturation.

Knowledge of the organizational and functional properties of hydrogen metabolism is pivotal to the construction of a framework supportive of a hydrogen-fueled low-carbon economy. Hydrogen metabolism relies on the mechanism of action of hydrogenases. In this study, we investigated the genomes of several industrially relevant acetogens of the genus (, , , , , , , sp.
