The value of cannabis stems from its euphoric activity offered by the unique phytocannabinoid tetrahydrocannabinol (THC). However, this is rapidly expanding beyond THC owing to other non-psychoactive phytocannabinoids with new bioactivities that will contribute to their development into clinically useful drugs. The discovery of the biosynthesis of major phytocannabinoids has allowed the exploration of their heterologous production by synthetic biology, which may lead to the industrial production of rare phytocannabinoids or novel synthetic cannabinoid pharmaceuticals that are not easily offered by cannabis plants. This review summarizes the biosynthesis of major phytocannabinoids in detail, the most recent development of their metabolic engineering in various systems, and the engineering approaches and strategies used to increase the yield.<\/jats:p>","DOI":"10.3390\/ijms22052454","type":"journal-article","created":{"date-parts":[[2021,2,28]],"date-time":"2021-02-28T20:43:32Z","timestamp":1614545012000},"page":"2454","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":44,"title":["The Biochemistry of Phytocannabinoids and Metabolic Engineering of Their Production in Heterologous Systems"],"prefix":"10.3390","volume":"22","author":[{"given":"Kaitlyn","family":"Blatt-Janmaat","sequence":"first","affiliation":[{"name":"Department of Chemistry, University of New Brunswick, Fredericton, NB E3B 5A3, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Qu","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of New Brunswick, Fredericton, NB E3B 5A3, Canada"},{"name":"Department of Chemical Engineering, University of New Brunswick, Fredericton, NB E3B 5A3, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"ElSohly, M.A. (2007).
