1.14.13.64	pharmacology	construction of a novel artificial pathway for arbutin biosynthesis in Escherichia colid. De novo biosynthesis of arbutin from simple carbon sources is established and a generalizable strategy for the biosynthesis of shikimate pathway derived chemicals is provided. Arbutin is a hydroquinone glucoside compound existing in various plants. It is widely used in pharmaceuticaland cosmetic industries owing to its well-known skin-lightening property as well as anti-oxidant, anti-microbial, and anti-inflammatory activities. A 4-hydroxybenzoate 1-hydroxylase gene from Candida parapsilosis CBS604 and a glucosyltransferase (arbutin synthase) gene from Rauvolfia serpentina are introduced into Escherichia coli lead to the production of 54.71 mg/l of arbutin from glucose. Further redirection of carbon flux into arbutin biosynthesis pathway by enhancing shikimate pathway genes enables production of 3.29 g/l arbutin, which is a 60-fold increase compared with the initial strain. Final optimization of glucose concentration added in the culture medium is able to further improve the titer of arbutin to 4.19 g/l in shake flasks experiments, which is around 77-fold higher than that of initial strain	-, 745691
