Nickel superoxide dismutase protects nitrogen fixation in Trichodesmium
Limnology and Oceanography Letters, 2022 Trichodesmium, a major diazotroph in tropical and subtropical oceans, provides a significant amount of bioavailable nitrogen in oligotrophic oceans. Remarkably, the cyanobacteria carry out nitrogen fixation and photosynthesis simultaneously under high ...

The Copper Chaperone for Superoxide Dismutase [PDF]
Journal of Biological Chemistry, 1997 Copper is distributed to distinct localizations in the cell through diverse pathways. We demonstrate here that the delivery of copper to copper/zinc superoxide dismutase (SOD1) is mediated through a soluble factor identified as Saccharomyces cerevisiae LYS7 and human CCS (copper chaperone for SOD).

Detoxification of superoxide without production of H2O2: antioxidant activity of superoxide reductase complexed with ferrocyanide [PDF]
proceedings of the national Academy of Sciences of the United
States of America, PNAS, 2006, pp.14750-5, 2015 The superoxide radical O(2)(-.) is a toxic by-product of oxygen metabolism. Two O(2)(-.) detoxifying enzymes have been described so far, superoxide dismutase and superoxide reductase (SOR), both forming H2O2 as a reaction product. Recently, the SOR active site, a ferrous iron in a [Fe(2+) (N-His)(4) (S-Cys)] pentacoordination, was shown to have the ...

A simple method for clinical assay of superoxide dismutase.
Clinical Chemistry, 1988 This assay for superoxide dismutase (SOD, EC 1.15.1.1) activity involves inhibition of nitroblue tetrazolium reduction, with xanthine-xanthine oxidase used as a superoxide generator.

Catalase, glutathione peroxidase, metabolic syndrome, superoxide dismutase
Majalah Kedokteran Bandung, 2012 Labor pain is part of a normal process, which often causes physiological and psychological stress to mother. These stress have impact to both mother and fetus. Largely (90%) labor comes with pain and in some cases severe pain.

Evolutionary relationships in superoxide dismutase [PDF]
FEBS Letters, 1975 Two distinct types of superoxide dismutase have been isolated from aerobic organisms. A blue-green Cu-Zn protein with a mol. wt of 32 000 and comprising two identical subunits has been obtained from a wide range of eukaryotes (e.g. [3,4]) while a pinkish-purple Mncontaining enzyme, also composed of identical subunits, has been isolated from eukaryotic ...

The enzyme-like catalytic activity of cerium oxide nanoparticles and its dependency on Ce3+ surface area concentration [PDF]
Nanoscale 10, 6971 - 6980 (2018), 2018 Cerium oxide nanoparticles are known to catalyze the decomposition of reactive oxygen species such as superoxide radical and hydrogen peroxide. Herein, we examine the superoxide dismutase (SOD) and catalase (CAT) mimetic catalytic activities of nanoceria and demonstrate the existence of generic behaviors.
