SseA, a 3-mercaptopyruvate sulfurtransferase fromEscherichia coli: crystallization and preliminary crystallographic data [PDF]
SseA, the translation product of the Escherichia coli sseA gene, is a 31 kDa protein endowed with 3-mercaptopyruvate:cyanide sulfurtransferase activity in vitro. As such, SseA is the prototype of a sulfurtransferase subfamily distinguished from the better known rhodanese sulfurtransferases, which display thiosulfate:cyanide sulfurtransferase activity ...

A critical role for cystathionine-β-synthase in hydrogen sulfide-mediated hypoxic relaxation of the coronary artery [PDF]
Hypoxia-induced coronary artery vasodilatation protects the heart by increasing blood flow under ischemic conditions, however its mechanism is not fully elucidated.

Inhibition of hydrogen sulfide biosynthesis sensitizes lung adenocarcinoma to chemotherapeutic drugs by inhibiting mitochondrial DNA repair and suppressing cellular bioenergetics [PDF]
Therapeutic manipulation of the gasotransmitter hydrogen sulfide (H(2)S) has recently been proposed as a novel targeted anticancer approach. Here we show that human lung adenocarcinoma tissue expresses high levels of hydrogen sulfide (H(2)S) producing ...

Hydrogen Sulfide and Polysulfides as Biological Mediators
Hydrogen sulfide (H2S) is recognized as a biological mediator with various roles such as neuromodulation, regulation of the vascular tone, cytoprotection, anti-inflammation, oxygen sensing, angiogenesis, and generation of mitochondrial energy.

Mitochondrial Sulfide Detoxification Requires a Functional Isoform O-Acetylserine(thiol)lyase C in Arabidopsis thaliana [PDF]
In non-cyanogenic species, the main source of cyanide derives from ethylene and camalexin biosyntheses. In mitochondria, cyanide is a potent inhibitor of the cytochrome c oxidase and is metabolised by the β-Cyanoalanine synthase CYS-C1, catalysing the ...

Discovery of an Inhibitor for Bacterial 3-Mercaptopyruvate Sulfurtransferase that Synergistically Controls Bacterial Survival [PDF]
H2S-producing enzymes in bacteria have been shown to be closely engaged in the process of microbial survival and antibiotic resistance. However, no inhibitors have been discovered for these enzymes, e.g., 3-mercaptopyruvate sulfurtransferase (MST). In the present study, we identified several classes of inhibitors for Escherichia coli MST (eMST) through

Regulation of the T-type Ca²⁺ channel Cav3.2 by hydrogen sulfide: Emerging controversies concerning the role of H₂S in nociception [PDF]
Ion channels represent a large and growing family of target proteins regulated by gasotransmitters such as nitric oxide, carbon monoxide and, as described more recently, hydrogen sulfide.

Hydrogen sulfide (H2S) is produced by the action of cystathionine-β-synthase (CBS), cystathionine-γ-lyase (CSE) or 3-mercaptopyruvate sulfurtransferase (3-MST). 3-MST converts 3-mercaptopyruvate (MPT) to H2S and pyruvate. H2S is recognized as an endogenous gaseous mediator with multiple regulatory roles in mammalian cells and organisms.
