Specific Enzymatic Chlorination of Tryptophan and Tryptophan Derivatives

1999
In 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 ...

The rate of tryptophan oxidation by tryptophan pyrrolase in the rat: effect of tryptophan loads and changes in tryptophan pyrrolase activity.

Acta vitaminologica et enzymologica, 1978
The in vivo assay of tryptophan pyrrolase gives best results when [ring-2-14C] tryptophan is used and rates of labelled CO2 production are measured at short times after the labelled tryptophan injection. Using this technique in conjunction with in vitro measurements, we find that both tryptophan pyrrolase activity and the liver tryptophan concentration
