  • Tryptamine producing tryptophan decarboxylase gene of plant origin
    Patent number: 5814520
    Abstract: In accordance with the present invention, there is provided an isolated and purified DNA fragment comprising a DNA sequence encoding a plant decarboxylase. Preferably, the DNA sequence encodes a plant tryptophan decarboxylase, more preferably from Catharanthus roseus. A 1747 bp cDNA clone was isolated by antibody screening of a cDNA expression library produced from poly A.sup.+ RNA found in developing seedlings of C. roseus. The invention also includes DNA sequences encoding a plant tryptophan decarboxylase which are synthetically produced to correspond substantially to the isolated and purified DNA sequence encoding the same enzyme. The nucleotide sequence of the synthetic DNA sequence is determined on the basis of codon degeneracy.
