Members of this family are tryptophan 2,3-dioxygenase, as confirmed by several experimental characterizations, and by conserved operon structure for many of the other members. This enzyme represents the first of a two-step degradation to L-kynurenine, and a three-step pathway (via kynurenine) to anthranilate plus alanine [Energy metabolism, Amino acids and amines].

Members of this family are tryptophan 2,3-dioxygenase, as confirmed by several experimental characterizations, and by conserved operon structure for many of the other members. This enzyme represents the first of a two-step degradation to L-kynurenine, and a three-step pathway (via kynurenine) to anthranilate plus alanine.

13.11.42 from EC) [] is a cytosolic haem protein which, together with the hepatic enzyme tryptophan 2,3-dioxygenase, catalyzes the conversion of tryptophan and other indole derivatives to kynurenines. The physiological role of IDO is not fully understood but is of great interest, because IDO is widely distributed in human tissues, can be up-regulated via cytokines such as interferon-gamma, and can thereby modulate the levels of tryptophan, which is vital for cell growth. The degradative action of IDO on tryptophan leads to cell death by starvation of this essential and relatively scarce amino acid. IDO is a haem-containing enzyme of about 400 amino acids. Site-directed mutagenesis showed His346 (P14902 from SWISSPROT) to be essential for haem binding, indicating that this histidine residue may be the proximal ligand. Mutation of Asp274 also compromised the ability of IDO to bind haem, suggesting that Asp274 may coordinate to haem directly as the distal ligand or is essential in maintaining the conformation of the haem pocket []. Other proteins that are evolutionarily related to IDO include yeast hypothetical protein YJR078w; and myoglobin from the red muscle of the archaeogastropodic molluscs, Nordotis madaka (Giant abalone) and Sulculus diversicolor [, ]. These unusual globins lack enzymatic activity but have kept the haem group.; GO: 0020037 heme binding; PDB: 2D0U_A 2D0T_A.
