It has been shown that tryptophan 2, 3-dioxygenase is expressed in a significant proportion of human tumors.
24.
In the same study, tryptophan 2, 3-dioxygenase expression by tumors prevented their rejection by immunized mice.

Several " in vitro " biochemical assays have been applied to monitor the catalytic activity of gamma-butyrobetaine dioxygenase.
27.
The enzyme belongs to the aci-reductone dioxygenase family of metal-binding enzymes, which are involved in methionine salvage.
