Significance: Protein persulfidation (the formation of RSSH), an evolutionarily conserved
oxidative posttranslational modification in which thiol groups in cysteine residues are …

Hydrogen sulfide (H2S) is a signaling molecule that regulates critical processes and allows
plants to adapt to adverse conditions. The molecular mechanism underlying H2S action …

Exposure to arsenic in contaminated drinking water is an emerging public health problem
that impacts more than 200 million people worldwide. Accumulating lines of evidence from …

The infected host deploys generalized oxidative stress caused by small inorganic reactive
molecules as antibacterial weapons. An emerging consensus is that hydrogen sulfide (H 2 …

Hydrogen sulfide (H2S), originally considered a toxic gas, is now a recognized
gasotransmitter. Numerous studies have revealed the role of H2S as a redox signaling …

Bacterial pathogens that cause invasive disease in the vertebrate host must adapt to host
efforts to cripple their viability. Major host insults are reactive oxygen and reactive nitrogen …

A zinc dithiolate complex supported by a [N3S2] ligand was studied as a model for zinc-
mediated thiolate-disulfide exchange, enabling isolation of a zinc-bound mixed-disulfide …

Persulfides (RSS–) are ubiquitous source of sulfides (S2–) in biology, and interactions
between RSS–and bioinorganic metal centers play critical roles in biological hydrogen …

Transition metals function as structural and catalytic cofactors for a large diversity of proteins
and enzymes that collectively comprise the metalloproteome. Metallostasis considers all …

Hydropersulfides (RSSH) are oxidized thiol (RSH) derivatives that have been shown to be
biologically prevalent with likely important functions (along with other polysulfur …
