Related to the respiratory NADH dehydrogenase complex (complex I), NDH transfers electrons originating from PSI to the plastoquinone pool while pumping protons across the thylakoid membrane, thereby increasing the amount of ATP produced per NADP+ molecule reduced4,5. NDH possesses 11 of the 14 ...
Photosystem II (PS II) of thylakoid membrane of photosynthetic organisms has drawn attention of researchers over the years because it is the only system on Earth that provides us with oxygen that we breathe. In the recent past, structure of PS II has been the focus of research in plant scie...
► The quaternary structure and function (the oxygen-affinity, cooperativity, and Bohr effect) of hemoglobin are independently modulated by the competition between the allosteric effects of oxygen and the opposing effects of heterotropic effectors on hemoglobin. ► The ligation state and the ...
Antioxidants are substances which prevent chemical changes caused by exposure to oxygen, in particular formation of free radical species. They have relevant applications in many domains, such as chemistry, materials sciences, biology, biochemistry and microbiology. The activity of antioxidants and their ...
The NMB0736 gene of Neisseria meningitidis serogroup B strain MC58 encodes the putative nitrogen regulatory protein, IIANtr (abbreviated to NM-IIANtr). The homologous protein present in Escherichia coli is implicated in the control of nitrogen assimilati
Ozonolysis reactions convert alkenes into carbon–oxygen compounds via C=C bond cleavage. Now the cleavage of alkenes to form carbon–nitrogen bonds—the aza version of ozonolysis, termed triazenolysis—has been developed. The reaction produces diamines from cyclic alkenes, while acyclic C=C bonds...
NOX2 is the prototypical member of the NADPH oxidase NOX superfamily and produces superoxide (O2•−), a key reactive oxygen species (ROS) that is essential in innate and adaptive immunity. Mutations that lead to deficiency in NOX2 activity correlate
A molecule is a collection of two or more atoms that are securely bound together by attractive forces or by chemical bonds. The term “atom” refers to the tiniest unit of matter that can be separated. The term “valency” refers to an element’s capacity for combination. ...

Oxygen surface mobility on oxides-supported metals has been studied for many years in our laboratory. The first step of the process is the activation of the oxygen molecule on the metal particle. Measurements of the kinetics of the adsorption–desorption of oxygen on metal surfaces were possible ...
