Chain A   (Q7K9G0_LEIMA | Q7K9G0)
molecular function
    GO:0016784    3-mercaptopyruvate sulfurtransferase activity    Catalysis of the reaction: 3-mercaptopyruvate + cyanide = pyruvate + thiocyanate.
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
    GO:0019499    cyanide metabolic process    The chemical reactions and pathways involving cyanide, NC-, the anion of hydrocyanic acid. Cyanide is a potent inhibitor of respiration, reacting with the ferric form of cytochrome aa3 and thus blocking the electron transport chain.
    GO:0019343    cysteine biosynthetic process via cystathionine    The chemical reactions and pathways resulting in the formation of cysteine, via the intermediate cystathionine.
cellular component
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
