Webtryptophan is first catalyzed into tryptamine by tryptophan decarboxylase (TDC; EC 4.1.1.28), followed by the catal-ysis of tryptamine by tryptamine 5-hydroxylase (T5H) to form serotonin (Schro¨der et al. 1999). However, in St. John’s wort (Hypericum perforatum), serotonin synthesis was reported to occur via 5-hydroxytryptophan as in Webtryptophan hydroxylase, a low-affinity (Km = 0.4 mM) enzyme that is abundant in the brain. Accordingly, whenever the brain tryp-tophan level rises, more serotonin is pro-duced (7). Rats fed or injected with tryp-tophan have higher brain serotonin levels than do controls.
