Over the last two decades, hydrogen sulfide (H2S) has emerged as an endogenous
regulator of a broad range of physiological functions. H2S belongs to the class of molecules …

Signaling by H2S is proposed to occur via persulfidation, a posttranslational modification of
cysteine residues (RSH) to persulfides (RSSH). Persulfidation provides a framework for …

Abstract Significance: Hydrogen sulfide (H2S) has been recognized as the third gaseous
transmitter alongside nitric oxide and carbon monoxide. In the past decade, numerous …

Over the last decade, hydrogen sulfide (H 2 S) has emerged as an important endogenous
gasotransmitter in mammalian cells and tissues. Similar to the previously characterized …

Neurotransmitters are important biochemical molecules that control behavioral and
physiological functions in central and peripheral nervous system. Therefore, the analysis of …

Magnetism plays a pivotal role in many biological systems. However, the intensity of the
magnetic forces exerted between magnetic bodies is usually low, which demands the …

The well-known tendency of sulfur to catenate is exemplified by an extensive series of
polysulfide dianions [Sn] 2−(n= 2–9) and related radical monoanions [Sn]˙−. The dianions …

Hydrogen sulfide can signal through 3 distinct mechanisms: 1) reduction and/or direct
binding of metalloprotein heme centers, 2) serving as a potent antioxidant through reactive …

The short C–H⋯ S contacts found in available structural data for both small molecules and
larger biomolecular systems suggest that such contacts are an often overlooked yet …

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