Functional characterization of a mycothiol peroxidase in Corynebacterium glutamicum that uses both mycoredoxin and thioredoxin reducing systems in the response to oxidative stress.
The MPx function is investigated by examining its potential peroxidase activity using different proton donors and it is proposed that the C. glutamicum MPx represents a new type of GPx that uses both mycoredoxin and Trx systems for oxidative stress response.
Functional characterization of a vanillin dehydrogenase in Corynebacterium glutamicum
The vdh deletion mutant partially lost its ability to grow on vanillin, indicating the presence of alternative VDH(s) in Corynebacterium glutamicum and contributes to understanding the VDH diversity from bacteria and the aromatic metabolism pathways in C. glutamum.
Trichoderma harzianum containing 1-aminocyclopropane-1-carboxylate deaminase and chitinase improved growth and diminished adverse effect caused by Fusarium oxysporum in soybean.
CosR is an oxidative stress sensing a MarR-type transcriptional repressor in Corynebacterium glutamicum.
CosR is a redox-sensitive regulator that senses peroxide stress to mediate oxidative stress resistance in C. glutamicum and is found to be more resistant to various oxidants and antibiotics.

It is reported that a Corynebacterium glutamicum methionine sulfoxide reductase A (CgMsrA) that belongs to the 3-Cys family of MsrAs plays important roles in oxidative stress resistance.
Confirmed and Potential Roles of Bacterial T6SSs in the Intestinal Ecosystem
Considering the distinct activities of T6SS in diverse bacteria residing in the intestine, it is suggested that T 6SS research in intestinal microbes may be beneficial for the future development of new medicines and clinical treatments.
A thioredoxin-dependent peroxiredoxin Q from Corynebacterium glutamicum plays an important role in defense against oxidative stress
The result that C. glutamicum PrxQ can prevent the damaging effects of adverse stresses by acting as thioredoxin-dependent monomeric peroxidase could be further applied to improve the survival ability and robustness of the important bacterium during fermentation process.

Cobalt phosphide formed on Co/C NTs and Co(3)O4/CNTs exhibits not only the highest activity, but also long-term stability in the PH3 decomposition reaction.
Graded Response of the Multifunctional 2-Cysteine Peroxiredoxin, CgPrx, to Increasing Levels of Hydrogen Peroxide in Corynebacterium glutamicum.
It is demonstrated for the first time that atypical 2-Cys CgPrx acts as both a Trx-dependent peroxidase and a molecular chaperone and plays a regulatory role in modulating the peroxide-mediated signaling cascades.
OhsR acts as an organic peroxide-sensing transcriptional activator using an S-mycothiolation mechanism in Corynebacterium glutamicum
This is the first report demonstrating that the regulatory OhsR specifically sensed OHPs stress and responded to it by activating a specific ohr gene under its control using an S-mycothiolated mechanism in vivo.
