Utility of Synechocystis sp. PCC glutaredoxin A as a platform to study high-resolution mutagenesis of proteins. [PDF]

open access: yesFrontiers in Plant Science, 2013
Glutaredoxin from the cyanobacterium Synechocystis sp. PCC 6803 is a small protein, containing only 88 amino acids, that participates in a large number of redox reactions, serving both as an electron donor for enzyme-catalyzed reductions and as a ...

Prediction of thioredoxin and glutaredoxin target proteins by identifying reversibly oxidized cysteinyl residues

open access: yesJournal of Integrative Bioinformatics, 2010
A significant part of cellular proteins undergo reversible thiol-dependent redox transitions which often control or switch protein functions. Thioredoxins and glutaredoxins constitute two key players in this redox regulatory protein network.

Deletion of glutaredoxin promotes oxidative tolerance and intracellular infection in Listeria monocytogenes [PDF]

open access: yesVirulence, 2019
Thiol-disulfide glutaredoxin systems of bacterial cytoplasm favor reducing conditions for the correct disulfide bonding of functional proteins, and therefore were employed by bacteria to defend against oxidative stress.

S-Denitrosylation: A Crosstalk between Glutathione and Redoxin Systems

open access: yesAntioxidants, 2022
S-nitrosylation of proteins occurs as a consequence of the derivatization of cysteine thiols with nitric oxide (NO) and is often associated with diseases and protein malfunction.

Tyr76 is essential for the cold adaptation of a class II glutaredoxin 4 with a heat‐labile structure from the Arctic bacterium Sphingomonas sp.

open access: yesFEBS Open Bio, 2023
Glutaredoxins (Grxs) are small proteins that share a well‐conserved thioredoxin (Trx)‐fold and participate in many biological processes. This study examined the cold adaptation mechanism of a Fe‐S cluster binding class II Grx4 (SpGrx4) from the ...

Distinct Shift in Beta-Cell Glutaredoxin 5 Expression Is Mediated by Hypoxia and Lipotoxicity Both In Vivo and In Vitro

open access: yesFrontiers in Endocrinology, 2018
Histomorphological and functional alterations in pancreatic islet composition directly correlate with hyperglycemia severity. Progressive deterioration of metabolic control in subjects suffering from type 2 diabetes is predominantly caused by impaired ...

Regulation of the Dimerization and Activity of SARS-CoV-2 Main Protease through Reversible Glutathionylation of Cysteine 300

open access: yesmBio, 2021
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent for coronavirus disease 2019 (COVID-19), encodes two proteases required for replication.

Intracellular glutathione pools are heterogeneously concentrated [PDF]

open access: yes, 2013
Glutathione is present in millimolar concentrations in the cell, but its relative distribution among cellular compartments remains elusive. We have chosen the endoplasmic reticulum (ER) as an example organelle to study compartment-specific glutathione ...

An NMR-Guided Screening Method for Selective Fragment Docking and Synthesis of a Warhead Inhibitor

open access: yesMolecules, 2016
Selective hits for the glutaredoxin ortholog of Brucella melitensis are determined using STD NMR and verified by trNOE and 15N-HSQC titration. The most promising hit, RK207, was docked into the target molecule using a scoring function to compare ...

Thiol-based redox regulation in sexual plant reproduction: new insights and perspectives

open access: yesFrontiers in Plant Science, 2013
The success of sexual reproduction in plants involves (i) the proper formation of the plant gametophytes (pollen and embryo sac) containing the gametes, (ii) the accomplishment of specific interactions between pollen grains and the stigma, which ...
