The purpose of the present invention is to provide a recombinant host cell which is capable of efficiently and easily producing a benzylisoquinoline alkaloid (BIA), in particular, tetrahydropapaveroline, 3-hydroxycoclaurine, 3-hydroxy-N-methylcoclaurine and/or reticuline, and a method for efficiently and easily producing these BIAs using the host cell. The present invention pertains to a recombinant host cell for producing a benzylisoquinoline alkaloid (BIA), in particular, tetrahydropapaveroline (THP), 3-hydroxycoclaurine, 3-hydroxy-N-methylcoclaurine and/or reticuline, in which a wild-type aromatic aldehyde synthase (AAS) or a mutant thereof and a wild-type aromatic amino acid decarboxylase (AAAD) or a mutant thereof are expressed.

Disclosed herein are methods that may be used for the synthesis of benzylisoquinoline alkaloids (“BIAs”) such as alkaloid morphinan. The methods disclosed can be used to produce thebaine, oripavine, codeine, morphine, oxycodone, hydrocodone, oxymorphone, hydromorphone, naltrexone, naloxone, hydroxycodeinone, neopinone, and/or buprenorphine. Compositions and organisms useful for the synthesis of BIAs, including thebaine synthesis polypeptides, purine permeases, and polynucleotides encoding the same, are provided.

Aspects of the invention include host cells that are engineered to produce benzylisoquinoline alkaloids (BIAs). The host cells include heterologous coding sequences for a variety of enzymes involved in synthetic pathways from starting compounds to BIAs of the host cell. Also provided are methods of producing the BIAs of interest by culturing the host cells under culture conditions that promote expression of enzymes encoded by the heterologous coding sequences of the host cells. Aspects of the invention further include compositions, e.g., host cells, starting compounds and kits, etc., that find use in methods of the invention.

Methods that may be used for the manufacture of the chemical compound (S)-norcoclaurine, (S)-norlaudanosoline, and (S)-norcoclaurine or (S)-norlaudanosoline synthesis intermediates are provided. (S)-Norcoclaurine, (S)-norlaudanosoline, and (S)-norcoclaurine or (S)-norlaudanosoline synthesis intermediates are useful as precursor products in the manufacture of certain medicinal agents.
