Methionine Residues in Exoproteins and Their Recycling by Methionine Sulfoxide Reductase AB Serve as an Antioxidant Strategy in Bacillus cereus [PDF]

open access: yes, 2017
During aerobic respiratory growth, Bacillus cereus is exposed to continuously reactive oxidant, produced by partially reduced forms of molecular oxygen, known as reactive oxygen species (ROS).

Induction of methionine-sulfoxide reductases protects neurons from amyloid β-protein insults in vitro and in vivo [PDF]

open access: yes, 2011
Amyloid β-protein (Aβ) self-assembly into toxic oligomers and fibrillar polymers is believed to cause Alzheimer’s disease (AD). In the AD brain, a high percentage of Aβ contains Met-sulfoxide at position 35, though the role this modification plays in AD ...

Methyl 4‐O‐Demethylbarbatate Destabilises HIF‐1α and Enhances Temozolomide Sensitivity in Glioma Cells

open access: yesCell Proliferation, EarlyView.
The lichen‐derived metabolite methyl 4‐O‐demethylbarbatate (Me‐4‐O‐DBA) suppresses glioma stemness, motility, and metabolic plasticity through inhibition of HIF‐1α signaling and synergistically enhances temozolomide activity, highlighting a potential strategy to target stemness‐driven therapeutic resistance in glioma.

The Neisseria gonorrhoeae Methionine Sulfoxide Reductase (MsrA/B) Is a Surface Exposed, Immunogenic, Vaccine Candidate [PDF]

open access: yes, 2019
Control of the sexually transmitted infection gonorrhea is a major public health challenge, due to the recent emergence of multidrug resistant strains of Neisseria gonorrhoeae, and there is an urgent need for novel therapies or a vaccine to prevent ...

Energetic dysregulations in psychotic disorders: Targets for new therapeutics

open access: yesThe FEBS Journal, EarlyView.
The present review synthesizes literature documenting aberrant energy production and use, specifically related to mitochondrial and redox dysregulation, in psychotic disorders. Findings from different levels of investigation—genetic, cellular, and in vivo imaging—converge on aberrant energy metabolism as a hallmark of psychotic disorders.

Reduction of DABS-L-methionine-dl-sulfoxide by protein methionine sulfoxide reductase from polymorphonuclear leukocytes: stereospecificity towards the l-sulfoxide

open access: yes, 1994
A new synthetic substrate for protein methionine sulfoxide reductase is proposed. We show that extracts from human polymorphonuclear leukocytes can reduce 4-dimethylaminoazobenzene-4'-sulfonyl-L-methionine-dl-sulfoxide [DABS-L-Met-dl-(O)] to the ...

Evolutionary Conserved and Divergent Responses to Copper Zinc Superoxide Dismutase Inhibition in Plants

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT After an initial evolution in a reducing environment, life got successively challenged by reactive oxygen species (ROS), especially during the great oxidation event (GOE) that followed the development of photosynthesis. Therefore, ROS are deeply intertwined into the physiological, morphological and transcriptional responses of most present‐day

Anaerobic respiration of host-derived methionine sulfoxide protects intracellular Salmonella from the phagocyte NADPH oxidase [PDF]

open access: yes
Intracellular Salmonella experiencing oxidative stress downregulates aerobic respiration. To maintain cellular energetics during periods of oxidative stress, intracellular Salmonella must utilize terminal electron acceptors of lower energetic value than ...

Structure and electron-transfer pathway of the human methionine sulfoxide reductase MsrB3

open access: yes, 2020
Introduction: The post-translational oxidation of methionine to methionine sulfoxide is a reversible process, enabling repair of oxidative damage to proteins and the use of sulfoxidation as a regulatory switch.
