|---|---|---|---|
| acetylxylan + 3 H2O = 3 acetic acid + xylan | catalyses the hydrolysis of acetyl groups from polymeric xylan, acetylated xylose, acetylated glucose, alpha-naphthyl acetate, p-nitrophenyl acetate but not from triacetylglycerol. Does not act on acetylated mannan or pectin. | Talaromyces purpureogenus | |
