Summaries for MPST Gene

Entrez Gene Summary for MPST Gene

  • This protein encoded by this gene catalyzes the transfer of a sulfur ion from 3-mercaptopyruvate to cyanide or other thiol compounds. It may be involved in cysteine degradation and cyanide detoxification. There is confusion in literature between this protein (mercaptopyruvate sulfurtransferase, MPST), which appears to be cytoplasmic, and thiosulfate sulfurtransferase (rhodanese, TST, GeneID:7263), which is a mitochondrial protein. Deficiency in MPST activity has been implicated in a rare inheritable disorder known as mercaptolactate-cysteine disulfiduria (MCDU). Alternatively spliced transcript variants encoding same or different isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]

GeneCards Summary for MPST Gene

MPST (Mercaptopyruvate Sulfurtransferase) is a Protein Coding gene. Among its related pathways are Sulfur metabolism and Metabolism. GO annotations related to this gene include thiosulfate sulfurtransferase activity and 3-mercaptopyruvate sulfurtransferase activity. An important paralog of this gene is TST.

UniProtKB/Swiss-Prot for MPST Gene

  • Transfer of a sulfur ion to cyanide or to other thiol compounds. Also has weak rhodanese activity. Detoxifies cyanide and is required for thiosulfate biosynthesis. Acts as an antioxidant. In combination with cysteine aminotransferase (CAT), contributes to the catabolism of cysteine and is an important producer of hydrogen sulfide in the brain, retina and vascular endothelial cells. Hydrogen sulfide H(2)S is an important synaptic modulator, signaling molecule, smooth muscle contractor and neuroprotectant. Its production by the 3MST/CAT pathway is regulated by calcium ions (By similarity).

GENATLAS Biochemistry:
mercaptopyruvate sulfurtransferase
UniProtKB/Swiss-Prot CatalyticActivity:
3-mercaptopyruvate + cyanide = pyruvate + thiocyanate.
UniProtKB/Swiss-Prot EnzymeRegulation:
By oxidative stress, and thioredoxin. Under oxidative stress conditions, the catalytic cysteine site is converted to a sulfenate which inhibits the MPST enzyme activity. Reduced thioredoxin cleaves an intersubunit disulfide bond to turn on the redox switch and reactivate the enzyme.
UniProtKB/Swiss-Prot Function:
Transfer of a sulfur ion to cyanide or to other thiol compounds. Also has weak rhodanese activity. Detoxifies cyanide and is required for thiosulfate biosynthesis. Acts as an antioxidant. In combination with cysteine aminotransferase (CAT), contributes to the catabolism of cysteine and is an important producer of hydrogen sulfide in the brain, retina and vascular endothelial cells.
