Overexpression of 2-mercaptoethanesulfonate biosynthesis genes comDE protects methane-producing archaea from oxidative stress

open access: yesJournal of Bacteriology
Coenzyme M (2-mercaptoethane sulfonate, CoM) is an essential low-molecular-weight thiol in methanogenic archaea (methanogens) that serves as a methyl carrier and as a component of CoM-S-S-CoB heterodisulfide comprising CoM and coenzyme B (7 ...

2,2′-[(1E,1′E)-1,2-Phenylenebis(azanylylidene)bis(methanylylidene)]bis(4-bromophenol)

open access: yesIUCrData, 2017
In the title compound, C20H14Br2N2O2, there are two intramolecular O—H...N hydrogen bonds forming S(6) ring motifs. The outer benzene rings are inclined to the central benzene ring by 39.09 (11) and 24.31 (11)°, and to one another by 37.12 (11)°.

Redox Control of 20S Proteasome Gating [PDF]

open access: yes, 2012
The proteasome is the primary contributor in intracellular proteolysis. Oxidized or unstructured proteins can be degraded via a ubiquitin-and ATP-independent process by the free 20S proteasome (20SPT).

Charge Transfer Chromophores Derived from 3d-Row Transition Metal Complexes

open access: yesMolecules, 2022
A series of new charge transfer (CT) chromophores of “α-diimine-MII-catecholate” type (where M is 3d-row transition metals—Cu, Ni, Co) were derived from 4,4′-di-tert-butyl-2,2′-bipyridyl and 3,6-di-tert-butyl-o-benzoquinone (3,6-DTBQ) in accordance with ...

Redox outside the Box: Linking Extracellular Redox Remodeling with Intracellular Redox Metabolism [PDF]

open access: yesJournal of Biological Chemistry, 2012
Aerobic organisms generate reactive oxygen species as metabolic side products and must achieve a delicate balance between using them for signaling cellular functions and protecting against collateral damage. Small molecule (e.g. glutathione and cysteine)- and protein (e.g.

Nitrate elimination by denitrification in hardwood forest soils of the Upper Rhine floodplain – correlation with redox potential and organic matter [PDF]

open access: yes, 2002
Denitrification in floodplains is a major issue for river- and groundwater quality. In the Upper Rhine valley, floodplain forests are about to be restored to serve as flood retention areas (polders).

Electronic Conductance Resonance in Non-Redox-Active Proteins [PDF]

open access: yes, 2020
Bioelectronics research has mainly focused on redox-active proteins because of their role in biological charge transport. In these proteins, electronic conductance is a maximum when electrons are injected at the known redox potential of the protein.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
