Beta glucogallin O galloyltransferase

In enzymology, a beta-glucogallin O-galloyltransferase (EC 2.3.1.90) is an enzyme that catalyzes the chemical reaction

2 1-O-galloyl-beta-D-glucose ⇌ D-glucose + 1-O,6-O-digalloyl-beta-D-glucose

Hence, this enzyme has one substrate, 1-O-galloyl-beta-D-glucose, and two products, D-glucose and 1-O,6-O-digalloyl-beta-D-glucose.

This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is 1-O-galloyl-beta-D-glucose:1-O-galloyl-beta-D-glucose O-galloyltransferase.
