Abstract: This invention provides a salutaridinol 7-O-acetyltransferase protein, a salutaridinol 7-O-acetyltransferase gene, and a sequence which is complementary thereto. This invention further provides a method for the production of thebaine comprising the steps of (i) contacting in vitro a protein having salutaridinol 7-O-acetyltransferase activity with salutaridinol and acetyl coenzyme A at pH 8 to 9, and (ii) recovering the thebaine thus produced.

Abstract: The present invention relates to methyl transfer enzymes involved in alkaloid biosynthesis in opium poppy. More particularly, the invention relates to proteins having (R,S)-reticuline 7-O-methyltransferase activity, to proteins having (R,S)-norcoclaurine 6-O-methyltransferase activity and to derivatives and analogues of these proteins. The invention also relates to nucleic acid molecules encoding the proteins, and their derivatives and analogues, and to their use in the production of methylated catechols and tetrahydrobenzylisoquinolines.

ID No. 15), or (ii) a fragment thereof having a length of at least 45 nucleotides, or (iii) a variant thereof, the sequence of which has at least 70% identity with the sequence of FIG. 9 (SEQ. ID No. 13) or FIG.

Abstract: The invention relates to a method for altering alkaloid biosynthesis in a plant, comprising: i) introducing into cells of a plant, an expressible exogenous nucleic acid comprising or consisting of an (S)-N-methylcoclaurine 3?-hydroxylase gene (cyp80b) or a derivative thereof, and ii) optionally propagating the plant, wherein expression of the exogenous nucleic acid in the plant or in its progeny results in altered levels of alkaloid biosynthesis.
