The reaction takes place at a specialized metal center that dramatically increases the acidity
of H2 and leads to a heterolytic splitting of the molecule which is strongly accelerated by the …

Hydrogenase proteins catalyze the reversible conversion of molecular hydrogen to protons
and electrons. The most abundant hydrogenases contain a [NiFe] active site; these proteins …

Photosynthetically produced hydrogen is an attractive, sustainable fuel. Semiartificial in vitro
techniques have been successfully implemented in which hydrogenases were attached to …

Traces of metal are required for fundamental biochemical processes, such as
photosynthesis and respiration. Cyanobacteria metal homeostasis acquires an important …

Fossil fuels are limited in nature and are not environmentally friendly, thus using them to
meet the rising energy needs is insufficient. Another major cause of global warming, which is …

Cyanobacteria are able to use solar energy for the production of hydrogen. It is generally
accepted that cyanobacterial NiFe-hydrogenases are reduced by NAD (P) H. This is in …

Chemical and fuel production by photosynthetic cyanobacteria is a promising technology but
to date has not reached competitive rates and titers. Genome-scale metabolic modeling can …

Symbiotic digestion of lignocellulose in the hindgut of higher termites is mediated by a
diverse assemblage of bacteria and archaea. During a large-scale metagenomic study, we …

Cyanobacteria have garnered interest as potential cell factories for hydrogen production. In
conjunction with photosynthesis, these organisms can utilize inexpensive inorganic …

Members of the candidate phylum Acetothermia are globally distributed and detected in
various habitats. However, little is known about their physiology and ecological importance …
