Grouped By:  Matching UniProtKB accession

UniProtKB description:  Esterase involved in the degradation of plant cell wall polysaccharides. Catalyzes the deacetylation of chemically acetylated xylan and native, steam-extracted xylan (PubMed:10846217). Seems to act in synergy with the xylanase XynD which produces xylo-oligosaccharides (PubMed:10846217). Also catalyzes the deesterification of methyl esters of 4-O-methyl-D-glucuronic acid (MeGlcA) side residues in synthetic glucuronoxylan methyl ester, suggesting that it may be able to cleave ester linkages between MeGlcA carboxyl and more complex alcohols, including linkages between hemicellulose and lignin alcohols in plant cell walls (PubMed:26216754).
