abstract |
The invention discloses enzymes involved in triterpene synthesis, and particularly relates to isolated polynucleotides. The polynucleotides encode enzymes comprising a carboxypeptidase-like protein, a methyltransferase and a glucosyltransferase. The enzymes are involved in the biosynthesis of beta-amyrin-derived triterpenes in plants and seeds. The invention also relates to construction of recombinant DNA constructs comprising all or a portion of the isolated polynucleotides. The polynucleotides are, in sense or antisense orientation, operably linked to at least one regulatory sequence. |
