Crystalline bacterial catalase [PDF]

open access: yesBiochemical Journal, 1947
It is now fifty-four years since Gottstein1 discovered that some bacteria are able to decompose hydrogen peroxide with evolution of gaseous oxygen, an activity he attributed to their possessing an intracellular enzyme which later came to be called ‘catalase’.

Improvements in antioxidant status after agraz consumption was associated to reductions in cardiovascular risk factors in women with metabolic syndrome

open access: yesCyTA - Journal of Food, 2021
In this study were evaluated the effects of the chronic consumption of agraz (Vaccinium meridionale) on antioxidant status and oxidative stress markers in 40 women with metabolic syndrome (MetS) (47.2 ± 9.4 years) through a double-blind, crossover design

DFT Investigation of Biocatalytic Mechanisms from pH-Driven, Multi-Enzyme, Biomimetic Behavior in CeO2 [PDF]

open access: yes, 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 ...

Location of catalase in crystalline peroxisomes of methanol-grown Hansenula polymorpha [PDF]

open access: yes, 1992
We have studied the intraperoxisomal location of catalase in peroxisomes of methanol-grown Hansenula polymorpha by (immuno)cytochemical means. In completely crystalline peroxisomes, in which the crystalline matrix is composed of octameric alcohol oxidase

Protective effects of bisoprolol against cadmium-induced myocardial toxicity through inhibition of oxidative stress and NF-κΒ signalling in rats

open access: yesJournal of Veterinary Research, 2021
The aim of the study was to investigate the mitigative effects of bisoprolol (BIS) in cadmium-induced myocardial toxicity on oxidative stress and its inhibitive effect on nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB) signalling ...

The structures of Micrococcus lysodeikticus catalase, its ferryl intermediate (compound II) and NADPH complex [PDF]

open access: yes, 2002
The crystal structure of the bacterial catalase from Micrococcus lysodeikticus has been refined using the gene-derived sequence both at 0.88 Angstrom resolution using data recorded at 110 K and at 1.5 Angstrom resolution with room-temperature data.

Prooxidative-Antioxidant Regulation in Patients with Serous Meningitis

open access: yesAktualʹnaâ Infektologiâ, 2016
Introduction. Serous meningitis takes a leading place among the central nervous system lesions, the share of which in neuroinfections structure ranges from 25 to 70 %. The imbalance in the functioning of prooxidant-antioxidant system plays a leading role

Moderate ethanol exposure during early ontogeny of the rat alters respiratory plasticity, ultrasonic distress vocalizations, increases brain catalase activity, and acetaldehyde-mediated ethanol intake

open access: yesFrontiers in Behavioral Neuroscience, 2022
Early ontogeny of the rat (late gestation and postnatal first week) is a sensitive period to ethanol’s positive reinforcing effects and its detrimental effects on respiratory plasticity. Recent studies show that acetaldehyde, the first ethanol metabolite,
