Assay of Tryptophan Decarboxylase from Catharanthus Roseus Plant Cell Cultures by High-performance Liquid Chromatography
Overview
Affiliations
An assay is described for the enzyme tryptophan decarboxylase from plant cell suspension cultures. It is based on the fluorometric detection of tryptamine by HPLC on a LiChrosorb RP-8 Select B column. Tryptophan decarboxylase from Catharanthus roseus was induced by transferring 14-day-old cells into an induction medium. Optimum activity was found 2 days after transfer, the increase being 5- to 10-fold. When kept at -15 degrees C the crude enzyme lost half its activity in about 7 days. The rate of the decarboxylation reaction was linear for at least 3 h at 35 degrees C.
