Purification and Properties of Rat Liver Tryptophan Oxygenase
Journal of Biological Chemistry, 1972 Abstract Tryptophan oxygenase has been purified from livers of glucocorticoid and l-tryptophan-treated rats. Homogeneity of the enzyme was established by polyacrylamide electrophoresis, sedimentation experiments, and immunodiffusion. Amino acid analyses reveal 6 residues of cysteine per enzyme molecule.

Journal of the Science of Food and Agriculture, EarlyView.Abstract Flammulina velutipes (enokitake) is an edible mushroom recognized for both its nutritional and medicinal properties. It exhibits a broad spectrum of biological activities, including antioxidant, anti‐inflammatory, antitumor, immunomodulatory, and gut microbiota‐regulating effects.

The Role of Polyphenols in Respiratory and Gut Health: From the Perspective of Gut‐Lung Axis
Phytotherapy Research, EarlyView.ABSTRACT The gut‐lung axis constitutes a dynamic, multidirectional communication platform between the gastrointestinal and respiratory tracts. Its complexity arises from the integrated crosstalk among the microbiota, immune system, and redox homeostasis, collectively influencing disease susceptibility and progression.

Effects of oestradiol and vitamin B6 on tryptophan metabolism in the rat: implications for the interpretation of the tryptophan load test for vitamin B6 nutritional status [PDF]
, 1983 1. The effects of the administration of oestradiol and vitamin B6 on tryptophan metabolism in the rat have been assessed by measurement of the release of 14CO2 from [14C]tryptophan, in vivo, in order to determine whether, and to what extent, the ...

, 2021 Some bacteria produce a potent antifungal agent (pyrrolnitrin) from tryptophan using four dioxygen dependent steps to outcompete other microbes. Each step of this process is catalyzed by an oxygenase encoded by the prnABCD cassette.

Mitochondrial interaction of fibrosis-protective 5-methoxy tryptophan enhances collagen uptake by macrophages [PDF]
, 2022 5-methoxy tryptophan (5-MTP) is an anti-fibrotic metabolite made by fibroblasts and epithelial cells, present in a micromolar concentrations in human blood, and is associated with the progression of fibrotic kidney disease, but the mechanism is unclear ...

Inhibition of tryptophan oxygenase in rat liver by steroid hormones [PDF]
Biochemical Journal, 1970 Pregnant women and normal humans treated with estrogens show evidence of increased conversion of L-tryptophan into nicotinic acid ribonucleotide. Increased activity of liver tryptophan oxygenase caused by the action of estrogens or elevated corticosteroid concentration is thought to be the cause. Progesterone caused a decrease in tryptophan oxygenase
