Metabolite Identification
Common Name3-Mercaptopyruvic acid
Description3-Mercaptopyruvic acid, also known as 3-mercapto-2-oxopropanoate or beta-thiopyruvate, belongs to the class of organic compounds known as alpha-keto acids and derivatives. These are organic compounds containing an aldehyde substituted with a keto group on the adjacent carbon. 3-Mercaptopyruvic acid is an intermediate in cysteine metabolism. 3-Mercaptopyruvic acid exists in all living organisms, ranging from bacteria to humans. Within humans, 3-mercaptopyruvic acid participates in a number of enzymatic reactions. In particular, 3-mercaptopyruvic acid and cyanide can be converted into pyruvic acid and thiocyanate; which is mediated by the enzyme 3-mercaptopyruvate sulfurtransferase. In addition, 3-mercaptopyruvic acid can be biosynthesized from 3-mercaptolactic acid; which is mediated by the enzyme L-lactate dehydrogenase. It has been studied as a potential treatment for cyanide poisoning, but its half-life is too short for it to be clinically effective. In humans, 3-mercaptopyruvic acid is involved in cystinosis, ocular nonnephropathic. Outside of the human body, 3-mercaptopyruvic acid has been detected, but not quantified in several different foods, such as lima beans, spinachs, shallots, mexican groundcherries, and white lupines. This could make 3-mercaptopyruvic acid a potential biomarker for the consumption of these foods.

Enzymes

Enzyme Details
1. Aspartate aminotransferase, cytoplasmic
General function:
Involved in transferase activity, transferring nitrogenous groups
Specific function:
Plays a key role in amino acid metabolism (By similarity).
Gene Name:
GOT1
Uniprot ID:
P17174
Molecular weight:
46247.14
Reactions
L-Cysteine + Oxoglutaric acid → 3-Mercaptopyruvic acid + DL-Glutamatedetails
Enzyme Details
2. Aspartate aminotransferase, mitochondrial
General function:
Involved in transferase activity, transferring nitrogenous groups
Specific function:
Catalyzes the irreversible transamination of the L-tryptophan metabolite L-kynurenine to form kynurenic acid (KA). Plays a key role in amino acid metabolism. Important for metabolite exchange between mitochondria and cytosol. Facilitates cellular uptake of long-chain free fatty acids.
Gene Name:
GOT2
Uniprot ID:
P00505
Molecular weight:
47517.285
Reactions
L-Cysteine + Oxoglutaric acid → 3-Mercaptopyruvic acid + DL-Glutamatedetails
Enzyme Details
3. Cystathionine gamma-lyase
General function:
Involved in pyridoxal phosphate binding
Specific function:
Catalyzes the last step in the trans-sulfuration pathway from methionine to cysteine. Has broad substrate specificity. Converts cystathionine to cysteine, ammonia and 2-oxobutanoate. Converts two cysteine molecules to lanthionine and hydrogen sulfide. Can also accept homocysteine as substrate. Specificity depends on the levels of the endogenous substrates. Generates the endogenous signaling molecule hydrogen sulfide (H2S), and so contributes to the regulation of blood pressure. Acts as a cysteine-protein sulfhydrase by mediating sulfhydration of target proteins: sulfhydration consists of converting -SH groups into -SSH on specific cysteine residues of target proteins such as GAPDH, PTPN1 and NF-kappa-B subunit RELA, thereby regulating their function.
Gene Name:
CTH
Uniprot ID:
P32929
Molecular weight:

4. 3-mercaptopyruvate sulfurtransferase
General function:

6. Thiosulfate sulfurtransferase
General function:
Involved in thiosulfate sulfurtransferase activity
Specific function:
Formation of iron-sulfur complexes, cyanide detoxification or modification of sulfur-containing enzymes. Other thiol compounds, besides cyanide, can act as sulfur ion acceptors. Also has weak mercaptopyruvate sulfurtransferase (MST) activity (By similarity). Together with MRPL18, acts as a mitochondrial import factor for the cytosolic 5S rRNA. Only the nascent unfolded cytoplasmic form is able to bind to the 5S rRNA.
