xyn11E

Gene
xyn11E
Protein
Endo-1,4-beta-xylanase Xyn11E
Organism
Paenibacillus barcinonensis
Length
210 amino acids
Function
Involved in depolymerization of xylan, a major component of the lignocellulosic substrates. Acts as an endo-xylanase that efficiently hydrolyzes the beta-1,4 glycosidic linkages between the xylopyranosyl residues in the main chain of the polymer, leading to the degradation of xylan into short oligosaccharides. Shows high activity toward branched xylans from both softwoods (arabinoxylans) and hardwoods (glucuronoxylans), showing the highest activity on beechwood xylan. Also hydrolyzes long xylooligosaccharides (with a degree of polymerization of greater than or equal to 5), while oligomers shorter than xylotetraose are not degraded. Is not active on carboxymethyl cellulose (CMC), Avicel, starch, polygalacturonic acid, laminarin, pectin, beta-D-barley glucan, or lichenan.
Similarity
Belongs to the glycosyl hydrolase 11 (cellulase G) family.
