Figure 2. Xyloglucan degradation patterns by purified cellulosomes, Xgh74A, Cel44O, or Cel9X.

The samples were analyzed by HPAEC-PAD. Xyloglucan at 3.5 g/L was incubated for 3 h at 37 °C with no enzyme (purple), with 6 mg/L (approx. 10 nM) of purified cellulosomes (black), with 2.5 nM of Xgh74A (red), with 2.5 nM of Cel44O (green), or with 2.5 nM of Cel9X (blue). “XGO₄”, “XGO₈”… “XGO₁₆” refer to xyloglucan oligosaccharides displaying 4, 8…16 glucosyl residues backbone, respectively.
