Symbiotic legume nodules employ both rhizobial exo- and endo-hydrogenases to recycle hydrogen produced by nitrogen fixation. [PDF]
PLoS ONE, 2010 BACKGROUND: In symbiotic legume nodules, endosymbiotic rhizobia (bacteroids) fix atmospheric N(2), an ATP-dependent catalytic process yielding stoichiometric ammonium and hydrogen gas (H(2)).

How the structure of the large subunit controls function in an oxygen-tolerant [NiFe]-hydrogenase [PDF]
, 2014 Salmonella enterica is an opportunistic pathogen that produces a [NiFe]-hydrogenase under aerobic conditions. In the present study, genetic engineering approaches were used to facilitate isolation of this enzyme, termed Hyd-5.

Heterologous expression and maturation of an NADP-dependent [NiFe]-hydrogenase: a key enzyme in biofuel production. [PDF]
PLoS ONE, 2010 Hydrogen gas is a major biofuel and is metabolized by a wide range of microorganisms. Microbial hydrogen production is catalyzed by hydrogenase, an extremely complex, air-sensitive enzyme that utilizes a binuclear nickel-iron [NiFe] catalytic site ...

[NiFeSe]-Hydrogenase Chemistry [PDF]
Accounts of Chemical Research, 2015 The development of technology for the inexpensive generation of the renewable energy vector H2 through water splitting is of immediate economic, ecological, and humanitarian interest. Recent interest in hydrogenases has been fueled by their exceptionally high catalytic rates for H2 production at a marginal overpotential, which is presently only matched

Integration of an [FeFe]-hydrogenase into the anaerobic metabolism of Escherichia coli
Biotechnology Reports, 2015 Biohydrogen is a potentially useful product of microbial energy metabolism. One approach to engineering biohydrogen production in bacteria is the production of non-native hydrogenase activity in a host cell, for example Escherichia coli. In some microbes,

Turning cellulose waste into electricity: hydrogen conversion by a hydrogenase electrode. [PDF]
PLoS ONE, 2013 Hydrogen-producing thermophilic cellulolytic microorganisms were isolated from cow faeces. Rates of cellulose hydrolysis and hydrogen formation were 0.2 mM L(-1) h(-1) and 1 mM L(-1) h(-1), respectively.

Proceedings of the Japan Academy, Series B, 2013 Hydrogenases are microbial enzymes which catalyze uptake and production of H(2). Hydrogenases are classified into 10 classes based on the electron carrier specificity, or into 3 families, [NiFe]-family (including [NiFeSe]-subfamily), [FeFe]-family and [Fe]-family, based on the metal composition of the active site. H(2) is heterolytically cleaved on the

New insights into [FeFe] hydrogenase activation and maturase function. [PDF]
PLoS ONE, 2012 [FeFe] hydrogenases catalyze H(2) production using the H-cluster, an iron-sulfur cofactor that contains carbon monoxide (CO), cyanide (CN(-)), and a dithiolate bridging ligand.
