The present disclosure provides for genetically modified organisms that provide numerous health benefits but also have an improved flavor profile and a more palatable aroma for the consumer of the organism.

The present disclosure provides for genetically modified organisms that provide numerous health benefits but also have an improved flavor profile and a more palatable aroma for the consumer of the organism.

Provided herein, among other things, is an engineered non-plant cell that produces a tropane alkaloid product, a precursor of a tropane alkaloid product, or a derivative of a tropane alkaloid product. A method for producing a tropane alkaloid, a precursor of a tropane alkaloid product, or a derivative of a tropane alkaloid product that makes use of the cell is also described.

The present invention generally related to a modified microbial cell capable of producing high levels of spermidine and/spermidine derivatives. The genetically modified microbial cell comprises at least one modification to native spermidine biosynthetic pathway via putrescine together with genes involved in the S-adenosylmethionine biosyntheticpathway.

Provided herein, among other things, is an engineered non-plant cell that produces a tropane alkaloid product, a precursor of a tropane alkaloid product, or a derivative of a tropane alkaloid product by means of a complement of biosynthetic enzymes and a complement of transporter proteins. A method for producing a tropane alkaloid, a precursor of a tropane alkaloid product, or a derivative of a tropane alkaloid product that makes use of the cell is also described.

The invention relates to production of polyamine analogs in yeast cells that are capable of producing at least one polyamine. The yeast cells also comprise a 4-coumarate:CoA ligase encoding gene, at least one polyamine N-acyltransferase gene and at least one polyamine synthase encoding gene but lacks a polyamine oxidase encoding gene or comprises a disrupted polyamine oxidase encoding gene. The yeast cells are capable of producing mono- and/or multi-substituted N-acylated polyamines.

The invention relates to production of polyamine conjugates in yeast cells that are capable of producing at least one polyamine. The yeast cells also comprise a polyamine:glutathione ligase encoding gene and at least one polyamine synthase encoding gene but lacks a polyamine oxidase encoding gene or comprises a disrupted polyamine oxidase encoding gene. The yeast cells are capable of producing various polyamine-glutathione conjugates.
