  1. Positional preference on acetylated xylo-oligosaccharides, calculated as the positional rate per relative amount of acetyl groups present (2-O, 3-O, 2,3-di-O acetylated Xylp and 3-O acetylated Xylp 2-O substituted with MeGlcA) at the start of hydrolysis. The data were normalized.
  2. 0, no activity; n.d., not determined.
