2.8.1.2 3-mercaptopyruvate sulfurtransferaseIUBMB Comments
The enzyme catalyses a transsulfuration reaction from 2-oxo-3-sulfanylpropanoate to an internal cysteine residue. In the presence of a dithiol such as reduced thioredoxin or dihydrolipoate, the sulfanyl sulfur is released as hydrogen sulfide. The enzyme participates in a sulfur relay process that leads to the 2-thiolation of some tRNAs and to protein urmylation by transferring sulfur between the NFS1 cysteine desulfurase (EC 2.8.1.7) and the MOCS3 sulfurtransferase (EC 2.8.1.11).

dithiothreitol
-
activates from 0.4 mM to 2 mM at a 3-mercaptopyruvate concentration of 0.625 mM, inhibition at 3 mM and 4 mM dithiothreitol
dithiothreitol
activates MST chiefly via reduction of a sulfenyl Cys247
thioredoxin
-
rat-reduced thioredoxin activates the enzyme 2.3fold after treatment with dithiothreitol, but dithiothreitol does not increase enzyme activity. The Escherichia coli thioredoxin-thioredoxin reductase-NADPH system more effectively increases enzyme activity to 4.5fold that of the control than the rat thioredoxin-thioredoxin reductase-NADPH system, which increases enzyme activity to 3fold that of the control
thioredoxin
Escherichia coli and rat thioredoxin activate the enzyme to 2.3- and 4.9fold the levels of activation by dithiothreitol-treated and -untreated enzyme, resp. Activation occurs via cleavage of the intersubunit bonds of the enzyme dimer at C154 and C263. Escherichia coli thioredoxin with substitution C35S forms adducts with the enzyme and activates after treatment with dithiotreitol
thioredoxin
a low redox potential sulfenate is reversibly formed at a catalytic site cysteine so as to inhibit MST, and thioredoxin-dependent reduction of the sulfenate restored the MST activity
thioredoxin
an intermolecular disulfide bond serves as a thioredoxin-dependent redox-sensing switch for the regulation of the enzymatic activity of 3-mercaptopyruvate sulfurtransferase. A cysteine residue on the surface of each subunit is oxidized to form an intersubunit disulfide bond so as to decrease MST activity, and thioredoxin-specific conversion of a dimer to a monomer increased MST acitvity
thioredoxin
Escherichia coli or rat reduced thioredoxin (Trx) cleaves the intersubunit disulfide bond to activate MST to 2.3- and 4.9fold the levels of activation of dithiothreitol (DTT)-treated and DTT-untreated MST, respectively. An intersubunit disulfide bond serves as a redox switch for enzyme activation
thioredoxin
-
rat-reduced thioredoxin activates the enzyme 2.3fold after treatment with dithiothreitol, but dithiothreitol does not increase enzyme activity. The Escherichia coli thioredoxin-thioredoxin reductase-NADPH system more effectively increases enzyme activity to 4.5fold that of the control than the rat thioredoxin-thioredoxin reductase-NADPH system, which increases enzyme activity to 3fold that of the control

malfunction
metabolism
physiological function
malfunction
-
mercaptolactate-cysteine disulfiduria is caused by enzyme defect with or without mental retardation
malfunction
3-mercaptopyruvate sulfurtransferase-knockout mice exhibit increased anxiety-like behaviors with an increase in serotonin level in the prefrontal cortex, but not with abnormal morphological changes in the brain
metabolism
the enzyme functions as an antioxidant protein and can produce H2S (or HS2) and SOx
metabolism
the enzyme interacts with proteins involved in Moco and FeS cluster biosynthesis like L-cysteine desulfurase NFS1 and the rhodanese-like protein MOCS3
metabolism
the enzyme is, together with cysteine aminotransferase, primarily responsible for H2S production in peripheral neurons
metabolism
3MST produces Cys-SSH and GSSH together with the potential signaling molecules hydrogen per- and tri-sulfide (H2S2 and H2S3). Cys-SSH and GSSH are produced in the brain of wild-type mice but not in those of 3MST-KO mice. The levels of total persulfurated species in the brain of 3MST-KO mice are less than 50% of that in the brain of wild-type mice. Cys-SSH and GSSH are produced in the presence of physiological concentrations of cysteine and glutathione, while those with longer sulfur chains, Cys-SSnH and GSSnH, are produced in the presence of lower than physiological concentrations of cysteine and glutathione
metabolism
a mitochondrial sulfur catabolic pathway catalyzes the complete oxidation of L-cysteine to pyruvate and thiosulfate. After transamination to 3-mercaptopyruvate, the sulfhydryl group from L-cysteine is transferred to glutathione by sulfurtransferase Str1 and oxidized to sulfite by the sulfur dioxygenase Ethe1. Sulfite is then converted to thiosulfate by addition of a second persulfide group by sulfurtransferase 1. This pathway is most relevant during early embryo development and for vegetative growth under light-limiting conditions
metabolism
-
the first step of sulfur transfer that leads to pyruvate release and formation of the persulfide intermediate is very efficient. It critically depends on the electrostatic contribution provided by the CGSGVT catalytic loop, any role of the so-called Ser/His/Asp triad can be excluded. In a concerted mechanism, the water-mediated protonation of the pyruvate enolate and S0 transfer from the deprotonated 3-mercaptopyruvate to the thiolate form of the catalytic cysteine occur concomitantly

physiological function
-
3MST and cytosolic and mitochondrial cysteine aminotransferases are localized to endothelial cells of the thoracic aorta and together enzymes produce H2S in this cell type. H2S is a smooth muscle relaxant released from endothelium
physiological function
-
changes in MST activity in response to variation in the supply of exogenous cysteine are suggestive of a role for the mercaptopyruvate pathway in the removal of excess intracellular cysteine, redox homeostasis, and antioxidant defense
physiological function
-
the enzyme serves not only as an enzyme in cysteine catabolism, but also as an antioxidant protein
physiological function
-
the enzyme serves not only as an enzyme in cysteine catabolism, but also as an antioxidant protein
physiological function
3-mercaptopyruvate sulfurtransferase coupled with cysteine (aspartate) aminotransferase is responsible for the production of H2S in the vascular endothelium of the thoracic aorta
physiological function
attenuation of 3MST by shRNA or pharmacological inhibition of 3MST significantly reduces endothelial cell proliferation,migration, and tube-like network formation. 3MST silencing also suppresses VEGF-induced endothelial cell migration. 3MST attenuation decreases mitochondrial respiration and mitochondrial ATP production, increases glucose uptake, and perturbes the entire endothelia cell metabolome
physiological function
-
cysteine desulfurase (IscS, EC 2.8.1.7), not 3-MST, is the primary source of endogenous H2S in Escherichia coli under anaerobic conditions. A significant decrease in H2S production under anaerobic conditions is observed in Escherichia coli upon deletion of IscS, but not in 3-MST-deficient bacteria
physiological function
embryo development of the thiosulfate sulfurtransferase Str1/sulfur dioxygenase Ethe1 double mutant is comparable with Str1 mutant lines and severyl impaired in comparison to wild-type. Embryogenesis is severely delayed in Str1 mutants and the Ethe1/Str1 double mutant
physiological function
histological observation reveals no remarkable findings in MST gene-deficient mice

COMMENTARY
LITERATURE
analysis
high-throughput screening of a large chemical library with a H2S-selective fluorescent probe, HSip-1, based on azamacrocyclic Cu2+ complex chemistry. HSip-1 can detect H2S in aqueous solution with high selectivity over biothiols, inorganic sulfur compounds, reactive oxygen species and reactive nitrogen species
medicine
medicine
a significantly higher level of 3-MST protein expression is observed in Down syndrome (trisomy of human chromosome 21) fibroblasts compared to cells from healthy control individuals. The excess 3-MST is mainly localized to the mitochondrial compartment. Pharmacological inhibition of 3-MST activity improves mitochondrial electron transport and oxidative phosphorylation parameters and enhances cell proliferation in Down syndrome cells but not in healthy control cells
medicine
after 24 h and 48 h incubation of MCF-7 cells with 2245 microM S-allyl-L-cysteine, induction of late apoptosis is observed. A decrease in cell viability is observed with increasing S-allyl-L-cysteine concentration and incubation time. S-allyl-L-cysteine has no significant cytotoxic effect on the MCF-7 cells upon all analyzed concentrations
medicine
colon cancer cells exposed to N-acetylcysteine for 24 h display increased expression and activity of MST and sulfide:quinone oxidoreductase. N-acetylcysteine persists at detectable levels inside the cells exposed to the drug for up to 24 h and sustains H2S synthesis by MST more effectively than cysteine
