Sensing and regulation of reactive sulfur species (RSS) in bacteria [PDF]

Current Opinion in Chemical Biology, 2023
The infected host deploys generalized oxidative stress caused by small inorganic reactive molecules as antibacterial weapons. An emerging consensus is that hydrogen sulfide (H2S) and forms of sulfur with sulfur-sulfur bonds termed reactive sulfur species (RSS) provide protection against oxidative stressors and antibiotics, as antioxidants.

The Reactive Sulfur Species Concept: 15 Years On [PDF]

Antioxidants, 2017
Fifteen years ago, in 2001, the concept of “Reactive Sulfur Species” or RSS was advocated as a working hypothesis. Since then various organic as well as inorganic RSS have attracted considerable interest and stimulated many new and often unexpected avenues in research and product development. During this time, it has become apparent that molecules with

Regulation of redox signaling by reactive sulfur species [PDF]

Journal of Clinical Biochemistry and Nutrition, 2021
Reactive sulfur species, such as cysteine persulfide, are produced endogenously at significant levels in cells and have rapidly emerged as common biomolecules. By virtue of improved analytical methods for detecting reactive persulfides, it has been demonstrated that these reactive molecules exhibit unique chemical properties and are present in various ...

Reactive Oxygen and Sulfur Species: Partners in Crime

Oxygen, 2022
The emergence of complexity requires cooperation, yet selection typically favors defectors that do not cooperate. Such evolutionary conflict can be alleviated by a variety of mechanisms, allowing complexity to emerge.

Reactive sulfur species are inactivated and excreted as trimethylsulfonium ion by thiopurine S-methyltransferase [PDF]

Redox Biology
Reactive sulfur species (RSS) play essential roles in cellular signaling, redox regulation, and defense against electrophilic stress. However, excessive RSS are cytotoxic and must be strictly regulated.

Reactive Sulfur Species Interact with Other Signal Molecules in Root Nodule Symbiosis in Lotus japonicus [PDF]

Antioxidants, 2020
Reactive sulfur species (RSS) function as strong antioxidants and are involved in various biological responses in animals and bacteria. Few studies; however, have examined RSS in plants.

Sulfide Homeostasis and Nitroxyl Intersect via Formation of Reactive Sulfur Species in Staphylococcus aureus [PDF]

mSphere, 2017
Staphylococcus aureus is a commensal human pathogen and a major cause of nosocomial infections. As gaseous signaling molecules, endogenous hydrogen sulfide (H2S) and nitric oxide (NO·) protect S.

Reactive sulfur species and their significance in health and disease. [PDF]

Biosci Rep, 2022
Abstract Reactive sulfur species (RSS) have been recognized in the last two decades as very important molecules in redox regulation. They are involved in metabolic processes and, in this way, they are responsible for maintenance of health.

Inorganic Reactive Sulfur-Nitrogen Species: Intricate Release Mechanisms or Cacophony in Yellow, Blue and Red?

Antioxidants, 2017
Since the heydays of Reactive Sulfur Species (RSS) research during the first decade of the Millennium, numerous sulfur species involved in cellular regulation and signalling have been discovered. Yet despite the general predominance of organic species in

Cardiac robustness regulated by reactive sulfur species. [PDF]

J Clin Biochem Nutr, 2022
The human myocardium contains robust cells that constantly beat from birth to death without being replaced, even when exposed to various environmental stresses. Myocardial robustness is thought to depend primarily on the strength of the reducing power to protect the heart from oxidative stress.
