FIG 6.

Hydrolysis actions of two AbFs on arabinose-based polysaccharides. (a) The natural substrates WAX, SA, and DSA were incubated with AbF51 or XynF for 12 h at 70°C. Hydrolysis products were analyzed by HPAEC-PAD. A, X1, X2, X3, and X4 refer to arabinose, xylose, xylobiose, xylotriose, and xylotetrose, respectively. Std, standard. (b) The chemical structures of SA and DSA. (c) The amounts of arabinose released by AbF51 and XynF on three substrates according to the signal areas of arabinose shown in panel a. AbF51 participant hydrolysis products were diluted 50-fold, and XynF participant products were diluted 200-fold with distilled water. Conc., concentration.
