A cell may include heterologous polynucleotides encoding a multienzyme complex involved in the metabolic pathway of phenylpropanoids and biosynthesis of a vanilloid or a hydroxybenzaldehyde precursor thereof, which multienzyme complex comprises enzymes for the biosynthesis of coumaric acid and a crotonase.

Provided herein are phenylalanine ammonia-lyase (PAL) variants produced by prokaryotes, wherein such prokaryotic PAL variant has a greater phenylalanine-converting activity and/or a reduced immunogenicity as compared to a wild-type PAL. Further provided are compositions of prokaryotic PAL and biologically active fragments, mutants, variants or analogs thereof, as well as methods for the production, purification, formulation, and use of such compositions for industrial and therapeutic purposes, e.g., treating hyperphenylalaninemia, including phenylketonuria, and other disorders, including cancer.

Genetically programmed microorganisms, such as bacteria, pharmaceutical compositions thereof, and methods of modulating and treating a disease and/or disorder are disclosed.

Genetically engineered bacteria, pharmaceutical compositions thereof, and methods of modulating and treating diseases associated with hyperphenylalaninemia are disclosed.

Genetically engineered bacteria, pharmaceutical compositions thereof, and methods of modulating and treating diseases associated with hyperphenylalaninemia are disclosed.

Phenylalanine ammonia-lyase (PAL) variants with a greater phenylalanine-converting activity and/or a reduced immunogenicity as compared to a wild-type PAL for therapeutic uses, including the treatment of adolescent subjects having PKU.

The present invention provides engineered phenylalanine ammonia-lyase (PAL) polypeptides and compositions thereof, as well as polynucleotides encoding the engineered phenylalanine ammonia-lyase (PAL) polypeptides.

Provided herein are methods for improving various traits in plants, such as in Vanilla sp. plants, by genetically-modifying the genome of plants, introducing heterologous sequences into the plants, or breeding plants with selected alleles. Such traits that can be improved by the methods and compositions of the present invention include an increase in levels of vanillin or one or more precursors thereof, reducing dehiscence, reducing the size of a rostellum or eliminating its presence, and increasing fungal resistance. Also disclosed herein are genetically-modified plants, extract from such plants or plant parts thereof, and methods of producing such plants or progeny thereof.

Disclosed herein are methods of bioproduction of enantiomerically pure or enantiomerically enriched 2-phenylglycinol or a derivative thereof by multiple enzyme-catalyzed chemical transformations in a one-pot reaction system.

The present disclosure discloses a recombinant microbe producing podophyllotoxin, or its derivatives, comprising genes encoding phenyl alanine ammonia-lyase (PAL), cinnamate-4-hydroxylate (C4H), 4-coumaroyl CoA-ligase (4CL), hydroxycinnamoyl-CoA quinate hydroxycinnamoyltransferase (HCT), p-coumaroyl quinate 3-hydroxylase (C3H), caffeoyl CoA O-methyltransferase (CCoAOMT), bifunctional pinoresinol-lariciresinol reductase (DIRPLR), secoisolariciresinol dehydrogenase (SDH), cytochrome P450 oxidoreductase CYP719, O-methyltransferase (OMT), cytochrome P450 oxidoreductase CYP71, and 2-oxoglutarate/Fe(II)-dependent dioxygenase (2-ODD). Also disclosed herein is a method for producing podophyllotoxin or its derivatives. Moreover, a method of treating cancer is also disclosed.
