Reaction: a 3-O-β-D-glucosyl-β-D-glucuronoside + phosphate = a β-D-glucuronoside + α-D-glucopyranose 1-phosphate
Other name(s): PBOR_13355 (locus name)
Systematic name: 3-O-β-D-glucopyranosyl-β-D-glucuronide:phosphate α-D-glucosyltransferase
Comments: The enzyme, characterized from the bacterium Paenibacillus borealis, catalyses a reversible reaction, transferring a glucosyl residue attached by a β(1,3) linkage to a D-glucuronate residue (either free or as a part of a β-D-glucuronide) to a free phosphate, generating α-D-glucopyranose 1-phosphate
