The IDO-2 protein plays a key role in cellular processes, catalyzing the initial and rate-limiting steps in the catabolism of the essential amino acid tryptophan in the kynurenine pathway. This enzymatic activity has been confirmed in multiple studies, establishing IDO-2 as a key regulator of tryptophan metabolism with important implications for immune regulation. IDO-2 Protein, Human (His) is the recombinant human-derived IDO-2 protein, expressed by E. coli , with C-6*His labeled tag.
