Figure 2.

Initial rate kinetics of hydrolysis and transglycosylation catalyzed by AtXTH31. Squares indicate the specific hydrolytic rate of XGO₂ (variably galactosylated XXXGXXXG-based oligosaccharides) to produce two XGO₁ molecules, and triangles indicate the specific transglycosylation rate of XGO₂ to produce XGO₃ plus XGO₁.
