Effect of allopurinol on phosphocreatine recovery and muscle function in older people with impaired physical function:a randomised controlled trial [PDF]

, 2020
Background: Allopurinol has vascular antioxidant effects and participates in purinergic signalling within muscle. We tested whether allopurinol could improve skeletal muscle energetics and physical function in older people with impaired physical ...

The enhancement of salt stress tolerance by salicylic acid pretreatment in Arabidopsis thaliana

Biologia Plantarum, 2020
Salicylic acid (SA) is an important plant hormone involved in the activation of defense responses against environmental stresses. However, there are still large of unsolved mysteries about how SA pretreatment affects the establishment of plant stress ...

Effects of OsAOX1a Deficiency on Mitochondrial Metabolism at Critical Node of Seed Viability in Rice

Plants, 2023
Mitochondrial alternative oxidase 1a (AOX1a) plays an extremely important role in the critical node of seed viability during storage. However, the regulatory mechanism is still poorly understood.

Detection of Alternative Oxidase Expression in Arabidopsis thaliana Protoplasts Treated with Aluminium

Bio-Protocol, 2015
Aluminium (Al), a non-essential metal widespread in the environment that is known to be toxic to humans as well as to plants, can cause damage not only to the roots but also to the aerial parts of plants.

Increasing NADH oxidation reduces overflow metabolism in Saccharomyces cerevisiae [PDF]

, 2007
Respiratory metabolism plays an important role in energy production in the form of ATP in all aerobically growing cells. However, a limitation in respiratory capacity results in overflow metabolism, leading to the formation of byproducts, a phenomenon ...

ROS/RNS Balancing, Aerobic Fermentation Regulation and Cell Cycle Control – a Complex Early Trait (‘CoV-MAC-TED’) for Combating SARS-CoV-2-Induced Cell Reprogramming

Frontiers in Immunology, 2021
In a perspective entitled ‘From plant survival under severe stress to anti-viral human defense’ we raised and justified the hypothesis that transcript level profiles of justified target genes established from in vitro somatic embryogenesis (SE) induction

Proton translocation in proteins [PDF]

, 1989
The active transport of protons across the low dielectric barrier imposed by biological membranes is accomplished by a plethora of proteins that span the ca. 40 Å of the phospholipid bilayer.

Analysis of Posttranslational Activation of Alternative Oxidase Isoforms [PDF]

Plant Physiology, 2017
Mitochondrial alternative oxidase (AOX) in plants is a non-proton-motive ubiquinol oxidase that is activated by redox mechanisms and 2-oxo acids. A comparative analysis of the AOX isoenzymes AOX1A, AOX1C, and AOX1D from Arabidopsis (Arabidopsis thaliana) revealed that cysteine residues, CysI and CysII, are both involved in 2-oxo acid activation, with ...

Comparison of the Kinetic Parameters of Alternative Oxidases From Trypanosoma brucei and Arabidopsis thaliana—A Tale of Two Cavities

Frontiers in Plant Science, 2021
The alternative oxidase (AOX) is widespread in plants, fungi, and some protozoa. While the general structure of the AOX remains consistent, its overall activity, sources of kinetic activation and their sensitivity to inhibitors varies between species. In

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

, 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
