特異性：This item recognizes Indoleamine-pyrrole 2,3 - dioxygenase (IDO), an enzyme responsible for the catabolism of tryptophan to N-formylkynurenine and kynurenine. With the exception of tryptophan oxidase in hepatocytes, IDO is the only enzyme that degrades the amino acid tryptophan to kynurenine. Chlamydial pathogens require tryptophan for growth. IDO can lower available tryptophan in target cells leading to conversion of the pathogen to persistant forms, with significance in the progression to chronic infection with its associated pathological effects.
