  1.14.19.68 | canadine-producing Saccharomyces cerevisiae strain harbors expression cassettes for seven heterologous enzymes: Papaper somniferum norcoclaurine 6-O-methyltransferase (Ps6OMT), Papaver somniferum 3'-hydroxy-N-methylcoclaurine 4'-O-methyltransferase 2 (Ps4'OMT), Papapver somniferum coclaurine N-methyltransferase (PsCNMT), Papaver somniferum berberine bridge enzyme (PsBBE), Thalictrum flavum scoulerine 9-O-methyltransferase (TfS9OMT), Thalictrum flavum canadine synthase (TfCAS), and Arabidopsis thaliana cytochrome P450 reductase 1 (CPR). The expression cassettes for the methyltransferases Ps6OMT, PsCNMT, and Ps4'OMT and the cytochrome P450 reductase CPR were chromosomally integrated, TfS9OMT and TfCAS are expressed from a high-copy plasmid, and PsBBE is expressed from a second high-copy plasmid |
