Regulation of dissimilatory sulfur oxidation in the purple sulfur bacterium Allochromatium vinosum [PDF]

, 2011
In the purple sulfur bacterium Allochromatium vinosum, thiosulfate oxidation is strictly dependent on the presence of three periplasmic Sox proteins encoded by the soxBXAK and soxYZ genes.

Enhancing cellular sulfane sulfur through β-glycosidase-activated persulfide donors: mechanistic insights and oxidative stress mitigation.

Chemical Communications, 2022
Sulfane sulfur species such as persulfides and polysulfides along with hydrogen sulfide protect cells from oxidative stress and are key members of the cellular antioxidant pool.

Functional studies on oligotropha carboxidovorans molybdenum–copper CO dehydrogenase produced in escherichia coli [PDF]

, 2018
The Mo/Cu-dependent CO dehydrogenase (CODH) from Oligotropha carboxidovorans is an enzyme that is able to catalyze both the oxidation of CO to CO2 and the oxidation of H2 to protons and electrons. Despite the close to atomic resolution structure (1.1 Å),

The Quantitative Significance of the Transsulfuration Enzymes for H2S Production in Murine Tissues [PDF]

, 2011
The enzymes of the transsulfuration pathway, cystathionine --synthase (CBS) and cystathionine --lyase (CSE), are important for the endogenous production of hydrogen sulfide (H2S), a gaseous signaling molecule. The relative contributions of CBS and CSE to

Therapeutic Efficacy of the Supersulfide Donor NAC‐S2 in Influenza Virus Pneumonia via Suppression of Excessive Inflammatory Responses

Microbiology and Immunology, EarlyView.
ABSTRACT Influenza pneumonia is characterized by excessive inflammatory responses that contribute to severe lung injury and mortality. Supersulfides, endogenously produced cysteine‐derived persulfides and polysulfides, exert potent antioxidant, anti‐ferroptotic, and anti‐inflammatory activities; however, their therapeutic potential after disease onset ...
