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 ...

Catalytically Potent and Selective Clusterzymes for Modulation of Neuroinflammation Through Single-Atom Substitutions [PDF]
Nature Communications,2020, 2020 Emerging artificial enzymes with reprogrammed and augmented catalytic activity and substrate selectivity have long been pursued with sustained efforts. The majority of current candidates rely on noble metals or transition metal oxides with rather poor catalytic activity compared with natural molecules.

Superoxide DismutasE in Spring Barley Caryopses
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2016 Superoxide dismutase (SOD) activity was determined in caryopses of spring barley grown in field trials in 2004–2006. A total set under study included five malting varieties with hulled grain, three waxy hull-less and hulled varieties (of US origin ...

DFT Investigation of Biocatalytic Mechanisms from pH-Driven, Multi-Enzyme, Biomimetic Behavior in CeO2 [PDF]
, 2021 There is considerable interest in the pH-dependent, switchable, biocatalytic properties of cerium oxide (CeO2) nanoparticles (CeNPs) in biomedicine, where these materials exhibit beneficial antioxidant activity against reactive oxygen species (ROS) at basic physiological pH but cytotoxic prooxidant activity in acidic cancer cell pH microenvironment ...

Increased peripheral lipid clearance in an animal model of amyotrophic lateral sclerosis [PDF]
The Journal of Lipid Research 48, 7 (07/2007) 1571-1580, 2007 Amyotrophic lateral sclerosis (ALS) is the most common adult motor neuron disease, causing motor neuron degeneration, muscle atrophy, paralysis, and death. Despite this degenerative process, a stable hypermetabolic state has been observed in a large subset of patients.

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 ...

Superoxide dismutase in anaerobes: survey [PDF]
Applied and Environmental Microbiology, 1978 Superoxide dismutase (SOD) was present in 23 of 28 strains of the genus Bacteroides tested. Several clostridia, anaerobic cocci, and anaerobic, grampositive, nonsporing rods contained measureable SOD, but the frequency of SOD occurrence was much lower than in the bacteroides.

The trail to superoxide dismutase [PDF]
Protein Science, 1998 City College of New York + Cornell Medical School + Duke. While a youngster, I was enthralled by the miracle of insect metamorphosis and followed the transformations of pet caterpillars to pupae and then to gloriously beautiful butterflies and moths. This led naturally to an interest in biology. but mere description was not totally satisfying.

Reaction Cycles of Halogen Species in the Immune Defense: Implications for Human Health and Diseases and the Pathology and Treatment of COVID-19 [PDF]
Cells 2020, 9(6), 1461, 2020 There is no vaccine or specific antiviral treatment for COVID-19. One current focus is drug repurposing research, but those drugs have limited therapeutic efficacies and known adverse effects. The pathology of COVID-19 is essentially unknown. It is therefore challenging to discover a successful treatment to be approved for clinical use.
