== Function == | |||
[https://www.uniprot.org/uniprot/XYN2_HYPJR XYN2_HYPJR] Glycoside hydrolase involved in the hydrolysis of xylan, a major plant cell wall hemicellulose made up of 1,4-beta-linked D-xylopyranose residues. Catalyzes the endohydrolysis of the main-chain 1,4-beta-glycosidic bonds connecting the xylose subunits yielding various xylooligosaccharides and xylose (PubMed:1369024, Ref.5). The catalysis proceeds by a double-displacement reaction mechanism with a putative covalent glycosyl-enzyme intermediate, with retention of the anomeric configuration (PubMed:7988708). Produces xylobiose and xylose as the main degradation products (PubMed:19556747).<ref>PMID:1369024</ref> <ref>PMID:19556747</ref> <ref>PMID:7988708</ref> <ref>PMID:1369024</ref> | |||
