Additionally, xylanase is the key ingredient in the dough conditioners s500 and us500 manufactured by Puratos . [15] These enzymes are used to improve the dough's workability and absorption of water. [15] In the future, xylanase may be used for the production of biofuel from unusable plant material. [16]
In molecular biology, Glycoside hydrolase family 10 is a family of glycoside hydrolases. Glycoside hydrolases EC 3.2.1. are a widespread group of enzymes that hydrolyse the glycosidic bond between two or more carbohydrates, or between a carbohydrate and a non-carbohydrate moiety.
Xylanase converts xylan into xylose. Given that plants contain up to 30% xylan, xylanase is important to the nutrient cycle. [25] The degradation of xylan and other hemicelluloses is relevant to the production of biofuels. Being less crystalline and more highly branched, these hemicelluloses are particularly susceptible to hydrolysis. [26] [27]
In molecular biology, glycoside hydrolase family 30 is a family of glycoside hydrolases. [citation needed]Glycoside hydrolases EC 3.2.1. are a widespread group of enzymes that hydrolyse the glycosidic bond between two or more carbohydrates, or between a carbohydrate and a non-carbohydrate moiety.
endo-1,3-β-Xylanase, EC 3.2.1.32 [xylanase (ambiguous), endo-1,3-β-xylosidase, 1,3-β-xylanase, 1,3-xylanase, β-1,3-xylanase, endo-β-1,3-xylanase, 1,3-β-D-xylan xylanohydrolase, xylan endo-1,3-β-xylosidase (misleading)] is an enzyme with systematic name 3-β-D-xylan xylanohydrolase.
Xylan 1,3-β-xylosidase (EC 3.2.1.72, 1,3-β-D-xylosidase, exo-1,3-β-xylosidase, β-1,3 ′-xylanase, exo-β-1,3 ′-xylanase, 1,3-β-D-xylan xylohydrolase) is an enzyme with systematic name 3-β-D-xylan xylohydrolase. [1] It catalyses the hydrolysis of successive xylose residues from the non-reducing termini of (1→3)-β-D-xylans.
Glucuronoarabinoxylan endo-1,4-beta-xylanase (EC 3.2.1.136, feraxan endoxylanase, feraxanase, endoarabinoxylanase, glucuronoxylan xylohydrolase, glucuronoxylanase, glucuronoxylan xylanohydrolase, glucuronoarabinoxylan 1,4-beta-D-xylanohydrolase) is an enzyme with systematic name glucuronoarabinoxylan 4-beta-D-xylanohydrolase.

This organism is of interest because it elaborates an enzyme, xylanase, which digests xylan, a heteropolymer of the pentose sugar xylose. By pretreating wood pulp with this enzyme, paper manufacturers can achieve comparable levels of whiteness with much less chlorine bleach. It has been described as Gram-negative, with a triple-layered wall. [5]
