LITERATURE
cloned into the pMyr vector and expressed as fusion protein with a myristylation sequence, which anchors the target protein to the yeast membrane. Fusion proteins (pSOS/SalAT and pMyr/SalR) coexpressed in the Saccharomyces cerevisiae cdc25H strain. SalR amplified from the recombinant plasmid SalR/pQE-30. The 0.9-kb DNA fragment ligated into an NheI/EcoRI-digested pET28a expression vector. SalR/pET28a expression construct transformed into Escherichia coli BL21(DE3)RIL

salutaridine synthase (PsSAS), salutaridine reductase (PsSAR) and salutaridinol acetyltransferase (PsSAT) are functionally coexpressed in Saccharomyces cerevisiae and optimization of the pH conditions allowed for productive spontaneous rearrangement of salutaridinol-7-O-acetate and synthesis of thebaine from (R)-reticuline. A 7-gene pathway for the production of codeine and morphine from (R)-reticuline is reconstituted. Yeast cell feeding assays using (R)-reticuline, salutaridine or codeine as substrates show that all enzymes are functionally coexpressed in yeast and that activity of salutaridine reductase and codeine-O-demethylase likely limit flux to morphine synthesis. The results of this study describe a significant advance for the synthesis of morphinans in Saccharomyces cerevisiae and pave the way for their complete synthesis in recombinant microbes
