In
enzymology, a beta-glucogallin-tetrakisgalloylglucose O-galloyltransferase (EC 2.3.1.143) is an enzyme that catalyzes the chemical reaction
.
- 1-O-galloyl-beta-D-glucose + 1,2,3,6-tetrakis-O-galloyl-beta-D-glucose D-glucose + 1,2,3,4,6-pentakis-O-galloyl-beta-D-glucose
Thus, the two
1,2,3,4,6-pentakis-O-galloyl-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:1,2,3,6-tetrakis-O-galloyl-beta-D-glucose 4-O-galloyltransferase. Other names in common use include beta-glucogallin-tetragalloylglucose 4-galloyltransferase, beta-glucogallin:1,2,3,6-tetra-O-galloylglucose, 4-O-galloyltransferase, beta-glucogallin:1,2,3,6-tetra-O-galloyl-beta-D-glucose, and 4-O-galloyltransferase.
