Cloned(Commentary)

Cloned (Comment) Organism
functional coexpression of pinoresinol-lariciresinol reductase from Forsythia intermedia (FiPLR), secoisolariciresinol dehydrogenase from Podophyllum pleianthum (PpSDH), and CYP719A23 together with a suitable NADPH-dependent reductase to ensure P450 activity in Escherichia coli. Escherichia coli is cotransformed with two plasmids, generating a modular coexpression system: a pCDFDuet-1 vector harboring the genes encoding for FiPLR and PpSDH (FiPLR-PpSDH module) and either a pETDuet-1 or pET28a-(+) vector harboring P450-redox partner combinations (P450-module), method, overview Dysosma pleiantha

additional information assembly of plant enzymes in Escherichia coli for the production of the valuable (-)-podophyllotoxin precursor (-)-pluviatolide. (-)-Pluviatolide is considered a crossroad compound in lignan biosynthesis, because the methylenedioxy bridge in its structure, resulting from the oxidation of (-)-matairesinol, channels the biosynthetic pathway toward the microtubule depolymerizer (-)-podophyllotoxin. This oxidation reaction is catalyzed with high regio- and enantioselectivity by a cytochrome P450 monooxygenase from Sinopodophyllum hexandrum (CYP719A23), which is expressed and optimized regarding redox partners in Escherichia coli. Pinoresinol-lariciresinol reductase from Forsythia intermedia (FiPLR), secoisolariciresinol dehydrogenase from Podophyllum pleianthum (PpSDH), and CYP719A23 are coexpressed together with a suitable NADPH-dependent reductase to ensure P450 activity, allowing for four sequential biotransformations without intermediate isolation. By using an Escherichia coli strain coexpressing the enzymes originating from four plants, (+)-pinoresinol is efficiently converted, allowing the isolation of enantiopure (-)-pluviatolide at a concentration of 137 mg/l (enantiomeric excess over 99% with 76% isolated yield), reaction scheme and method, overview Dysosma pleiantha
