| Enzyme Function | FUNCTION: Xyloglucan acetyltransferase that catalyzes the acetylation of fucosylated Gal residues on xyloglucan side chains (PubMed:30083810). Predominantly catalyze 6-O-monoacetylation of Gal residues in the Fuc-Gal-Xyl trisaccharide side chains of xyloglucan oligomers (PubMed:30083810). Involved in xyloglucan specific O-acetylation in roots and rosette leaves (PubMed:22086088). {ECO:0000269|PubMed:22086088, ECO:0000269|PubMed:30083810}. |
