Specific Enzymatic Chlorination of Tryptophan and Tryptophan Derivatives
1999In the search for an alternative to chemical halogenation reactions using the free halogens, a novel type of halogenating enzymes was detected. In contrast to haloperoxidases, these NADH-dependent halogenases are specific. Tryptophan halogenase which catalyses the regioselective chlorination of tryptophan to 7-chlorotryptophan can also chlorinate ...

Spectroscopic determination of tryptophan and tyrosine in proteins.
Biochemistry, 1967A rapid method for the determination of tryptophan in proteins is presented. It is based on ab- sorbance measurements at 288 and 280 mp of the protein dissolved in 6 M guanidine hydrochloride. Blocked tryptophanyl (N-acetyl-L-tryptophanamide) and tyrosyl

Tryptophan Metabolism in Rabbits
2003Enzyme activities involved in tryptophan metabolism along the kynurenine pathway were studied in male New Zealand white rabbits. Activities are expressed both as specific activity and per g of fresh tissue. Liver tryptophan 2,3-dioxygenase activity (TDO), when assayed in either the absence (holoenzyme) or presence of added haematin (apoenzyme), did not
