| Enzyme Function | FUNCTION: Xylan acetyltransferase required for 2-O- and 3-O-monoacetylation of xylosyl residues in xylan (PubMed:29569182). Catalyzes the 2-O-acetylation of xylan, followed by nonenzymatic acetyl migration to the O-3 position, resulting in products that are monoacetylated at both O-2 and O-3 positions (By similarity). {ECO:0000250|UniProtKB:Q9LY46, ECO:0000269|PubMed:29569182}. |
