Probing the Catalytic Promiscuity of a Regio- and Stereospecific C-Glycosyltransferase from<i>Mangifera indica</i>
The catalytic promiscuity of the novel benzophenone C‐glycosyltransferase, MiCGT, which is involved in the biosynthesis of mangiferin from Mangifera indica, was explored. MiCGT exhibited a robust capability to regio‐ and stereospecific C‐glycosylation of 35 structurally diverse druglike scaffolds and simple phenolics with UDP‐glucose, and also formed O‐ and N‐glycosides. Moreover, MiCGT was able to

synthesis of acylphloroglucinol 3‐C‐glucosides from 2‐O‐glucosides was exploited using a novel C‐glycosyltransferase (MiCGTb) from Mangifera indica. Compared with previously characterized CGTs, MiCGTb exhibited unique de‐O‐glucosylation promiscuity and high regioselectivity toward structurally diverse 2‐O‐glucosides of acylphloroglucinol and achieved high yields of C‐glucosides even with a catalytic amount
