EC 2.3.1.90     
Accepted name: β-glucogallin O-galloyltransferase
Reaction: 2 1-O-galloyl-β-D-glucose = D-glucose + 1-O,6-O-digalloyl-β-D-glucose
Systematic name: 1-O-galloyl-β-D-glucose:1-O-galloyl-β-D-glucose O-galloyltransferase
Comments: β-Glucogallin can act as donor and as acceptor. Digalloylglucose can also act as acceptor, with the formation of 1-O,2-O,6-O-trigalloylglucose
