Metabolite Identification
Common NameHydrogen sulfide
DescriptionHydrogen sulfide, also known as sulfide or H2S, belongs to the class of inorganic compounds known as other non-metal sulfides. These are inorganic compounds containing a sulfur atom of an oxidation state of -2, in which the heaviest atom bonded to the oxygen belongs to the class of other non-metals. Hydrogen sulfide exists as a solid, possibly soluble (in water), and possibly neutral molecule. Hydrogen sulfide exists in all living species, ranging from bacteria to humans. Hydrogen sulfide is a potentially toxic compound.

Enzymes

General function:
Amino acid transport and metabolism
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 (By similarity).
