Developing the Escherichia coli Platform for Efficient Glycosylation of Steviol Glycosides through Metabolic Engineering
Rare steviol glycosides (SGs), characterized by superior sensory profiles and promising bioactivities, are high-intensity sweeteners derived from Stevia rebaudiana. Their intrinsically low abundance limits extraction yields, while in vitro bioconversion is limited by the availability of UDP-glucose (UDPG). Here, an E...
