Solomon,a A. Teplitsky,a S. Shulami,b G. Zolotnitsky,b Y. Shohamb* and G. Shohama* Background: Sequence alignment suggests that xylanases evolved from two ancestral proteins and therefore can be grouped into two families, designated F and G. Family F enzymes show no sequence similarity with any known structure and their architecture is unknown.

Due to the diversity in the chemical structures of xylans derived from the cell walls of wood, cereal or other plant materials, a large variety of xylanases with various hydrolytic activities, physicochemical properties and structures are known. Therefore, several aspects of xylan structure remain unclear. XYLANASE: XYLAN HYDROLYZING ENZYME Over 100 years ago the role of enzymes in the breakdown of xylan was observed by Hopper-Seyler (Bastawde 1992). Xylanases, the xylan hydrolyzing enzymes, are ubiquitous and diverse by nature (Collins et al. 2005).
Microbial xylanases with different multiplicities and properties are reported. The substrate of xylanases, xylan, is a major structural polysaccharide in plant cells, and is the second most abundant polysaccharide in nature, accounting for approximately one-third of all renewable organic carbon on earth [1]. The enzymes that catalyze this process include xylanases that degrade xylan, a β-1,4-xylose polymer that is decorated with various sugars. Although xylanases efficiently hydrolyze unsubstituted
Xylanase is the name given to a class of enzymes which degrade the linear polysaccharide beta-1,4-xylan into xylose, thus breaking down hemicellulose, one of the major components of plant cell walls. As such, it plays a major role in micro-organisms thriving on plant sources for the degradation of plant matter into usable nutrients. Search results for xylanase at Sigma-Aldrich.

Diverse forms of these enzymes exist, displaying varying folds, mechanisms of action, substrate specificities, hydrolytic activities (yields, rates and products) and physicochemical characteristics. Xylanase (EC 3.2.1.8) is any of a class of enzymes that degrade the linear polysaccharide xylan into xylose, thus breaking down hemicellulose, one of the major components of plant cell walls. As such, it plays a major role in micro-organisms thriving on plant sources for the degradation of plant matter into usable nutrients. Protein structure of xylanase.

*Please select more than one item to compare The xylanase folds in an ((Y/P)~ barrel (TIM-barrel), with additional helices and loops arranged at the “top” forming the active site cleft. In its overall shape, the R simplicissimum xylanase structure is similar to other family 10 xylanases, but its active site cleft is much shallower and wider.
