Electrochemical deprotonation of phosphate on stainless steel [PDF]
, 2004 Voltammetric experiments performed in phosphate buffer at constant pH 8.0 on platinum and stainless steel revealed clear reduction currents, which were correlated to the concentrations of phosphate.

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 ...

Respiratory membrane endo-hydrogenase activity in the microaerophile Azorhizobium caulinodans is bidirectional. [PDF]
PLoS ONE, 2012 BACKGROUND: The microaerophilic bacterium Azorhizobium caulinodans, when fixing N(2) both in pure cultures held at 20 µM dissolved O(2) tension and as endosymbiont of Sesbania rostrata legume nodules, employs a novel, respiratory-membrane endo ...

Frontiers in Microbiology, 2022 The spoilage of vacuum-packed meat by Clostridium estertheticum complex (CEC), which is accompanied by or without production of copious amounts of gas, has been linked to the acetone–butyrate–ethanol fermentation, but the mechanism behind the variable ...

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 ...

Structural insight on the mechanism of an electron-bifurcating [FeFe] hydrogenase
eLife, 2022 Electron bifurcation is a fundamental energy conservation mechanism in nature in which two electrons from an intermediate-potential electron donor are split so that one is sent along a high-potential pathway to a high-potential acceptor and the other is ...

Nitrogen Fixation Mutants of the Actinobacterium Frankia Casuarinae CcI3 [PDF]
, 2017 Frankia is a representative genus of nitrogen-fixing (N2-fixing) actinobacteria; however, the molecular mechanisms underlying various phenomena such as the differentiation of a N2 fixation-specific structure (vesicle) and the regulation of N2 fixation ...

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.

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.

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 ...
