The enzyme tryptophan decarboxylase (TDC) (EC 4.1.1.28) catalyses a key step in the biosynthesis of terpenoid indole alkaloids in C. roseus by converting tryptophan into tryptamine. Hardly any tdc mRNA could be detected in hormone-independent callus

The involvement of O-sulphate esters in the directed O-methylation was investigated in vitro with a dialysed ‘high-speed’ supernatant from rat liver as the enzyme preparation and the catechol compound 3,4-dihydroxybenzoic acid as the substrate. T
