Metabolic turnover of hydrogen sulfide [PDF]
Frontiers in Physiology, 2012 More than 15 years have passed since hydrogen sulfide (H2S) emerged as a biological signaling molecule – initially, in the nervous and vascular systems through the modulation of N-methyl d-aspartate (NMDA) receptors and the activation of transmembrane receptor potential (TRP)- and ATP-dependent K+ (KATP)-channels (Abe and Kimura, 1996; Hosoki et al ...

Hydrogen metabolism in aerobic hydrogen-oxidizing bacteria [PDF]
Biochimie, 1978 A survey on organisms able to use molecular hydrogen as electron donor in the energy-yielding process is presented. In the group of the aerobic hydrogen-oxidizing bacteria so far two types of hydrogenases have been encountered, a NAD-reducing, soluble enzyme (H2 : NAD oxidoreductase) and a membrane-bound enzyme unable to reduce pyridine nucleotides ...

Computational analysis of an HCCI engine fuelled with hydrogen/hydrogen peroxide blends [PDF]
, 2022 Copyright © 2022 The Authors. In the current work, Chemkin Pro's HCCI numerical model is used in order to explore the feasibility of using hydrogen in a dual fuel concept where hydrogen peroxide acts as ignition promoter.

Hydrogen Peroxide Metabolism in Yeasts [PDF]
Applied and Environmental Microbiology, 1988 A catalase-negative mutant of the yeast Hansenula polymorpha consumed methanol in the presence of glucose when the organism was grown in carbon-limited chemostat cultures. The organism was apparently able to decompose the H 2 O 2 generated in the oxidation of methanol ...

Hydrogen Sulfide Metabolism and Pulmonary Hypertension [PDF]
Cells, 2021 Pulmonary hypertension (PH) is a severe and multifactorial disease characterized by a progressive elevation of pulmonary arterial resistance and pressure due to remodeling, inflammation, oxidative stress, and vasoreactive alterations of pulmonary arteries (PAs).

Hydrogen Metabolism in Higher Plants [PDF]
Plant Physiology, 1964 Kinetin interacts with light in the promotion of the germination of Grand Rapids lettuce seeds. In the dark, there is only a slight stimulating effect. The optimal condition for the study of this interaction was the use of very small quantities of light given after 7 hours of soaking.

Hydrogenases and Hydrogen Metabolism of Cyanobacteria [PDF]
Microbiology and Molecular Biology Reviews, 2002 SUMMARY Cyanobacteria may possess several enzymes that are directly involved in dihydrogen metabolism: nitrogenase(s) catalyzing the production of hydrogen concomitantly with the reduction of dinitrogen to ammonia, an uptake hydrogenase (encoded by hupSL) catalyzing the consumption of hydrogen produced by the nitrogenase, and a
