| Background: | 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. |
| UniProt Protein Function: | MPST: Transfer of a sulfur ion to cyanide or to other thiol compounds. Also has weak rhodanese activity. May have a role in cyanide degradation or in thiosulfate biosynthesis. |
| UniProt Protein Details: | Protein type:Amino Acid Metabolism - cysteine and methionine; EC 2.8.1.2; Mitochondrial; Transferase Chromosomal Location of Human Ortholog: 22q12.3 Cellular Component: neuron projection Biological Process: cyanate catabolic process; response to toxin |
