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.

Formate and hydrogen in hydrothermal vents and their use by extremely thermophilic methanogens and heterotrophs

Frontiers in Microbiology, 2023
Extremely thermophilic methanogens in the Methanococci and heterotrophs in the Thermococci are common in deep-sea hydrothermal vents. All Methanococci use H2 as an electron donor, and a few species can also use formate.

Functional and Biogenetical Heterogeneity of the Inner Membrane of Rat-Liver Mitochondria [PDF]

, 1971
Rat liver mitochondria were fragmented by a combined technique of swelling, shrinking, and sonication. Fragments of inner membrane were separated by density gradient centrifugation.

Cobaloxime-Based Artificial Hydrogenases [PDF]

Inorganic Chemistry, 2014
Cobaloximes are popular H2 evolution molecular catalysts but have so far mainly been studied in nonaqueous conditions. We show here that they are also valuable for the design of artificial hydrogenases for application in neutral aqueous solutions and report on the preparation of two well-defined biohybrid species via the binding of two cobaloxime ...

Electron transport phosphorylation in rumen butyrivibrios: unprecedented ATP yield for glucose fermentation to butyrate. [PDF]

, 2015
From a genomic analysis of rumen butyrivibrios (Butyrivibrio and Pseudobutyrivibrio sp.), we have re-evaluated the contribution of electron transport phosphorylation (ETP) to ATP formation in this group.

Effect of hydrogenase on the corrosion of mild steel [PDF]

, 2007
Losses due to corrosion are evaluated at 4% of the GDP of industrialised countries and biocorrosion may be responsible for 10% of these costs [1]. Whereas the general mechanism of anaerobic corrosion, involving iron sulphur deposits, seems now well ...

Erythrocytes as Carriers of Therapeutic Enzymes. [PDF]

, 2020
Therapeutic enzymes are administered for the treatment of a wide variety of diseases. They exert their effects through binding with a high affinity and specificity to disease-causing substrates to catalyze their conversion to a non-noxious product, to ...

Immunological relationship among hydrogenases [PDF]

Journal of Bacteriology, 1989
We examined the immunological cross-reactions of 11 different hydrogenase antigens with 9 different hydrogenase antibodies. Included were antibodies and antigens of both subunits of the hydrogenases of Bradyrhizobium japonicum and Thiocapsa roseopersicina. The results showed a strong relationship among the Ni-Fe dimeric hydrogenases.

ADP-dependent Phosphofructokinases in Mesophilic and Thermophilic Methanogenic Archaea [PDF]

, 2001
Phosphofructokinase (PFK) is a key enzyme of the glycolytic pathway in all domains of life. Two related PFKs, ATP-dependent and PPi-dependent PFK, have been distinguished in bacteria and eucarya, as well as in some archaea.
