Gene Source Screening as a Tool for Naringenin Production in Engineered Saccharomyces cerevisiae.

ABSTRACT: Flavonoids are plant secondary metabolites with great potential in the food industry. Metabolic engineering of Saccharomyces cerevisiae is a sustainable production technique. However, the current naringenin production yield is low because of inefficient enzymatic activity. Hence, this study uses gene source screening as a tool to identify the best gene source for enzymes such as 4-coumarate: coenzyme ligase (4CL) and chalcone synthase (CHS). For the first time, the 4CL gene from Medicago truncatula and the CHS gene from Vitis vinifera were expressed in S. cerevisiae, and this combination provided the highest yield of naringenin, which was 28-fold higher as compared to the reference strain. The combinations obtained similar performance in the Y-28 strains, where
