Enzymatic β-elimination in natural product O- and C-glycoside deglycosylation
Nature Communications, 2023 Biological degradation of natural product glycosides involves, alongside hydrolysis, β-elimination for glycosidic bond cleavage. Here, we discover an O-glycoside β-eliminase (OGE) from Agrobacterium tumefaciens that converts the C3-oxidized O-β-d ...

Properties of Pyridoxine Glucoside
THE JOURNAL OF VITAMINOLOGY, 1971 Intact pyridoxine glucoside showed about 20% of microbiological activity of equivalent mole of pyridoxine for Saccharomyces carlsbergensis 4228 ATCC 9080. The activity was gradually increased accompanied with the prolonged incubation. It seems that pyridoxine glucoside is hydrolyzed to pyridoxine and glucose by α-glucosidase of Saccharomyces ...
