The regulation of tryptophan pyrrolase activity by tryptophan

Advances in Enzyme Regulation, 1966
Abstract Tryptophan pyrrolase accumulates in the livers of hydrocortisone-treated rats as the inactive apoenzyme. Treatment with tryptophan activates the apoenzyme by conjugating it with hematin and permitting its conversion to the active, reduced holoenzyme form of tryptophan pyrrolase.

The hydroxylation of tryptophan

Archives of Biochemistry and Biophysics, 1992
Products of the chemical hydroxylation of tryptophan by Fenton and Udenfriend reactions are similar to those obtained by ionizing radiation. When tryptophan is exposed to either of these systems, a mixture of four hydroxytryptophans, oxindole-3-alanine, and N-formylkynurenine is formed.

Free Tryptophan in Plasma and Brain Tryptophan Metabolism

Nature, 1972
SYNTHESIS in the brain of the putative transmitter 5-hydroxytryptamine (5HT) is influenced by the concentration of tryptophan; the rate limiting step in 5HT synthesis is the hydroxylation of tryptophan1 by tryptophan hydroxylase, which is normally unsaturated with substrate2.
