The reference genome of Bacillus subtilis was first sequenced and annotated 25 years ago. At that time, some 42% of the coding sequences could not be assigned a function. In the present annotated update, 15% of the CDS remain functionless. An important contribution of newly identitied functions has been attributed to nucleic acid modifying enzymes and ...

Abstract Hydrogen peroxide (H2O2) is a reactive oxygen species (ROS) and a key modulator of the development and architecture of the root system under physiological and adverse environmental conditions. Nitric oxide (NO) and hydrogen sulphide (H2S) also exert myriad functions on plant development and signalling. Accumulating pieces of evidence show that

HIF-1 Has a Central Role in Caenorhabditis elegans Organismal Response to Selenium
Selenium is a trace element for most organisms; its deficiency and excess are detrimental. Selenium beneficial effects are mainly due to the role of the 21st genetically encoded amino acid selenocysteine (Sec).

The mitochondrial coenzyme Q junction and complex III: biochemistry and pathophysiology
Coenzyme Q (CoQ) is the electron‐carrying lipid in the mitochondrial electron transport system. In mammals, it is the electron acceptor for mitochondrial dehydrogenases involved in metabolic pathways ranging from ATP synthesis, amino acid, and fatty acid oxidation to nucleotide biosynthesis, methylation, and hydrogen sulfide detoxification.

Signaling by reactive molecules and antioxidants in legume nodules
Summary Legume nodules are symbiotic structures formed as a result of the interaction with rhizobia. Nodules fix atmospheric nitrogen into ammonia that is assimilated by the plant and this process requires strict metabolic regulation and signaling. Reactive oxygen species (ROS) and reactive nitrogen species (RNS) are involved as signal molecules at all

Hydrogen sulfide is a physiologically relevant signalling molecule. However, circulating levels of this highly biologically active substance have to be maintained within tightly controlled limits in order to avoid toxic side effects.

Human mitochondrial persulfide dioxygenase is potently and reversibly inhibited by nitric oxide
Hydrogen sulfide (H2S) regulates multiple human physiological processes, its reactivity and range of action being tightly controlled through regulation of H2S-synthesizing and -detoxifying enzymes. H2S detoxification is mainly achieved by a mitochondrial sulfide detoxifying pathway including persulfide dioxygenase (PDO).

Oxidative Stress: Molecular Mechanisms, Diseases, and Therapeutic Targets
Oxidative stress occurs when the reactive oxygen species (ROS) production overwhelms the ROS scavenging, which lead to genomic instability, epigenetic regulation, proteostasis imbalance, and lipid peroxidation, subsequently causing the occurrence and development of numerous diseases. ABSTRACT Although the physiological level of reactive oxygen species (

Supersulfide biology and translational medicine for disease control
Abstract For decades, the major focus of redox biology has been oxygen, the most abundant element on Earth. Molecular oxygen functions as the final electron acceptor in the mitochondrial respiratory chain, contributing to energy production in aerobic organisms. In addition, oxygen‐derived reactive oxygen species including hydrogen peroxide and nitrogen
