SYNTHESIS OF GLYCOSYLATED SPHINGOID BASES OF INTEREST OR ANALOGUES THEREOF
The present invention relates to a method for producing a glycosylated sphingoid base of interest or an analogue thereof, the method comprising providing an internalized exogenous precursor and a genetically modified cell, wherein one or more glycosylation reactions can be performed on the exogenous precursor in the genetically modified cell, the genetically modified cell comprising one or more nucleic acid sequences encoding one or more glycosyltransferase enzymes.
Novel Flavone Hydroxylases, Microorganism for Synthesizing Flavone C-Glycoside Compounds, and Use Thereof
Provided are novel flavone hydroxylases, a microorganism for synthesizing flavone C-glycoside compounds, and use thereof. The present inventor obtains novel flavones hydroxylates PhF2H and PhF3′H by cloning, which belong to cytochrome P450 hydroxylates and have the function of hydroxylating specific positions of compounds. Further, the present inventor, by modifying the enzymes and combining a C-glycoside glycosyltransferase and assembly of a synthesis pathway of a flavone precursor, efficiently synthesizes flavone C-glycoside compounds such as oriention, isooriention, vitexin and isovitexin, and related intermediates such as eriodictyol and 2-hydroxynaringenin in the synthesis pathway thereof in an artificial recombinant expression system.

Engineered microorganisms for enhanced use of oligosaccharides
Disclosed herein are genetically modified microorganisms and related methods for enhanced utilization of oligosaccharides and improved productivity of compounds derived from the metabolism of the oligosaccharides. The microorganisms described herein have altered activities of plasma membrane ATPase protein (PMA1) and/or one or more extracellular glucose sensors, namely, sucrose non-fermenting protein (SNF3), restores glucose transport protein (RGT2), and G protein-coupled receptor 1 protein (GPR1). These genetic modifications provide the microorganisms an increased ability to utilize an oligosaccharide to produce a compound of interest, particularly, tagatose, 2′-fucosyllactose, and psicose. Methods of culturing the microorganisms in the presence of such oligosaccharides to produce the products of interest are also provided.
