Recently, a gene for a 7-dimethylallyltryptophan synthase (7-DMATS) was identified in Aspergillus fumigatus and its enzymatic function was proven biochemically. In this study, the behaviour of 7-DMATS towards aromatic substrates was investigated and compared with that of the 4-dimethylallyltryptophan synthase

Testes weight, plasma FSH and LH concentration and pineal methylating capacity were compared in hamsters housed under either long (LD14:10) or short (LD8:16) photoperiods. Hamsters housed for 14 weeks under short photoperiod showed gonadal atrophy, which was complete after 6

Pineal glands were incubated in the presence of [3H] methoxytryptophan with and without methoxamine, epinephrine, and norepinephrine. The beta-adrenoceptor-stimulated pineal glands were capable of converting methoxytryptophan to methoxytryptamine, melatonin, methoxyindole acetic acid, and methoxytryptophol, albeit in small quantities. Only methoxyindole

Until now the day/night and seasonal rhythmicity in the synthesis of 5-methoxyindoles (MI) is thought to be regulated by environmental factors, especially photoperiod and temperature. Endogenous factors are also implicated in the generation of N-acetyltransferase and hydroxyindole-O-methyltransferase activity rhythms. In

Markedly increased melatonin levels in plasma have been observed in response to tryptophan administration. This post-tryptophan melatonin increase has been attributed to the duodenum. Because extra-pineal sources of melatonin may be important in interpreting the meaning of altered melatonin production
