β-xylosidase (NCU01900) and β-glucosidase (NCU00130) activities on glucopyranosyl-xylose. GX synthesized in vitro used as a substrate contained some traces of xylose and G1P. Purified β-xylosidase and β-glucosidase were incubated with GX substrate mixture in 1× PBS, pH 7.4 buffer. The purified proteins were omitted in the control reaction. Chromatograms are displayed with 2 minute-offsets between samples. GX, glucopyranosyl-xylose; G1P, glucose-1-phosphate.
