Acetylesterase that acts as an exo-deacetylase (PubMed:24140638). Shows activity towards naphtyl acetate, triacetin, as well as towards glucose- and xylose acetates (PubMed:18978092, Ref.2). Liberates acetic acid from xylo-oligomers (PubMed:18978092, Ref.2, PubMed:24140638). an acetyl ester + H2O = acetate + an aliphatic alcohol + H(+) Optimum pH is 5.5. Optimum temperature is 50 degrees Celsius. Expression is induced by sophorose, cellulose, oat spelt xylan, lactose, and arabinose. N-glycosylated. Belongs to the carbohydrate esterase CE16 family.
