METHOD FOR MASS PRODUCTION OF QUERCETIN-3-O-GALACTOSE USING PEF3GALGT GENE IN ESCHERICHIA COLI

摘要

The present invention relates to a composition for producing a quercetin-3-O-galactose compound containing an expression vector including a gene for coding a Petunia hybrida UDP-dependent glycosyltransferase (PeF3GalGT) protein, and an expression vector including a UDP-galactose synthetic gene, and a Escherichia coli in which a UDP-galactose epimerase (galE) gene is deleted, and to a Escherichia coli transformed by an expression vector including gene for coding the PeF3GalGT protein, and an expression vector including the galE gene to produce a quercetin-3-O-galactose compound.
