Method for Preparing 3amp;horbar;Ｏamp;horbar;Xylosyl Quercetin from Quercetin Using Microorganism Mutants

摘要

microbial variants of the present invention using quercetin (quercetin) from 3 - O -xylene to room quercetin (3- O -xylosyl quercetin) relates to a method of manufacturing a, more specifically xylose UDP- biosynthesis (UDP-xylose biosynthtic pathway) encoding an enzyme involved in the glycosyl transferase gene and Reyes (glycosyltransferase) is introduced gene coding for 3- O in quercetin - using microbes and microbial mutant variants with a production capacity of xylene in room quercetin from quercetin 3 - O - relates to a process for preparing a room quercetin in xylene. Produced by using a microorganism mutant gene has been introduced a gene encoding a glycosyl transferase and raise encoding the enzyme involved in trehalose biosynthesis pathway and UDP- shadow of the invention 3- O - xylene in chamber Quercetin can be developed as drugs for the treatment of cancer have a anti-cancer effect, anti-aging, anti-stress effect, such as whitening and may be useful as a composition for food and cosmetic because. ;
