regioselectivity is different from that of typical acetylxylan esterases (AcXEs). In aqueous medium saturated with vinyl acetate, the CE‐2 enzymes catalyzed transacetylation to the same position, i.e., to the primary hydroxyl group of mono‐ and disaccharides. Xylose and xylooligosaccharides did not serve as acetyl group acceptors, therefore the CE‐2 enzymes appear to be 6‐O‐deacetylases.
