The hydroxylation of tryptophan
Archives of Biochemistry and Biophysics, 1992Products 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.

Prevention of allogeneic fetal rejection by tryptophan catabolism.
Science, 1998In 1953 Medawar pointed out that survival of the genetically disparate (allogeneic) mammalian conceptus contradicts the laws of tissue transplantation.

Activation of the Ah Receptor by Tryptophan and Tryptophan Metabolites
Biochemistry, 1998The aryl hydrocarbon receptor (AhR) is a ligand-dependent transcription factor that mediates many of the biological and toxicological actions of a variety of hydrophobic natural and synthetic chemicals, including the environmental contaminant 2,3,7, 8-tetrachlorodibenzo-p-dioxin (TCDD, dioxin). A variety of indole-containing chemicals, such as indole-3-

Tryptophan in health and disease.
Advances in Clinical Chemistry, 2020Tryptophan (TRP), an essential amino acid in mammals, is involved in several physiological processes including neuronal function, immunity, and gut homeostasis. In humans, TRP is metabolized via the kynurenine and serotonin pathways, leading to the generation of biologically active compounds, such as serotonin, melatonin and niacin.

The regulation of tryptophan pyrrolase activity by tryptophan
Advances in Enzyme Regulation, 1966Abstract 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.

Tryptophan uptake and tryptophan oxygenase activity in mice
Biochemical and Biophysical Research Communications, 1970Abstract Groups of mice were injected intraperitoneally with L-tryptophan, 1 mg/gm body weight, and maintained at room temperature (22° C) or exposed to acute heat stress (36° C). In the heat-stressed animals, plasma tryptophan levels were lower at each time interval studied when compared with room temperature controls; however, both hepatic ...

Detection of Tryptophan to Tryptophan Energy Transfer in Proteins
The Protein Journal, 2004Förster resonance energy transfer (FRET) studies usually involve observation of intensity or lifetime changes in the donor or acceptor molecule and usually these donor and acceptor molecules differ (heterotransfer). The use of polarization to monitor FRET is far less common, although it was one of the first methods utilized. In 1960, Weber demonstrated

Abstract Tryptophan possesses two sets of emissions, each one of which has one short-lived emission and one long-lived emission. The excitation by π-π absorption at 280 mμ gives u.v. fluorescence and blue phosphorescence under certain conditions, e.g. frozen in an aqueous solution containing glucose or methanol.
