WebIndoleamine 2,3-dioxygenase (IDO) is an enzyme that is responsible for converting tryptophan to kynurenines. IDO is expressed by a wide variety of tissues and IDO can be upregulated by interferon gamma. IDO modulates levels of the amino acid tryptophan, which is vital for cell growth, but is also involved in the suppression of the immune response. The systematic name of this enzyme class is L-tryptophan:oxygen 2'-oxidoreductase (side-chain-cleaving). Other names in common use include indole-3-alkane alpha-hydroxylase, tryptophan side-chain alpha,beta-oxidase, tryptophan side chain oxidase II, tryptophan side-chain oxidase, TSO, indolyl-3-alkan alpha-hydroxylase, tryptophan side chain oxidase type I, TSO I, TSO II, and tryptophan side chain oxidase.
