Spinocerebellar Ataxia Type 2 Is Associated with the Extracellular Loss of Superoxide Dismutase but Not Catalase Activity

open access: yesFrontiers in Neurology, 2017
BackgroundSpinocerebellar ataxia type 2 (SCA2) is an inherited and still incurable neurodegenerative disorder. Evidence suggests that pro-oxidant agents as well as factors involved in antioxidant cellular defenses are part of SCA2 physiopathology.AimTo ...

Electrochemical reduction of oxygen catalyzed by Pseudomonas aeruginosa [PDF]

open access: yes, 2010
Pseudomonas aeruginosa has already been shown to catalyze oxidation processes in the anode compartment of a microbial fuel cell. The present study focuses on the reverse capacity of the bacterium, i.e. reduction catalysis. Here we show that P. aeruginosa

Non-heme manganese catalase – The ‘other’ catalase [PDF]

open access: yesArchives of Biochemistry and Biophysics, 2012
Non-heme manganese catalases are widely distributed over microbial life and represent an environmentally important alternative to heme-containing catalases in antioxidant defense. Manganese catalases contain a binuclear manganese complex as their catalytic active site rather than a heme, and cycle between Mn(2)(II,II) and Mn(2)(III,III) states during ...

Decreased myocardial injury and improved contractility after administration of a peptide derived against the alpha-interacting domain of the L-type calcium channel. [PDF]

open access: yes, 2014
BackgroundMyocardial infarction remains the leading cause of morbidity and mortality associated with coronary artery disease. The L-type calcium channel (IC a-L) is critical to excitation and contraction.

Inhibition of TXNRD or SOD1 overcomes NRF2-mediated resistance to β-lapachone [PDF]

open access: yes, 2020
Alterations in the NRF2/KEAP1 pathway result in the constitutive activation of NRF2, leading to the aberrant induction of antioxidant and detoxification enzymes, including NQO1.

SPECTROSCOPY OF CATALASE [PDF]

open access: yesJournal of General Physiology, 1937
Catalase is resistant to oxidizing agents; e.g., ferricyanide. It is also resistant to reducing agents; e.g., catalytically activated hydrogen, hydrosulfite, ferrotartrate, cysteine. The hemin group of the enzyme will combine with cyanide, sulfides, nitric oxide, fluoride. It will not combine with carbon monoxide. Catalase is therefore a ferric complex.

Statistical study of aca-talasemia, a review of thirty-eight cases appearing in the literatures [PDF]

open access: yes, 1959
1. With a view to grasp more simply and clearly the characteristics of this disease and in order to find a clue for prompt discovery of cases when encountered in future, the authors undertook a statistical study of the cases already reported by various ...
