XIP proteins have a (β/α) 8-barrel crystal structure displaying structural features typical of the GH 18 xylanases. They have no chitinase activity due to structural differences in the region homologous to the active site of chitinases ( Payan et al 2003 ). from Bacillus subtilis(generally known as the xylanase A, or XynA) as determined by x-ray crystallography. The structure is typical of most G11 xylanases and, contains two twisted b-sheets forming a so called "jellyroll" foldwhich looks remarkably like a right hand, in which the individualb-strands 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.

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.

[ 1] Fungi and bacteria produce xylanase, and it's produced by insects, crustaceans like snails, and even seeds. [ 2] Mammals, including humans, do not produce xylanase, but some of our gut bacteria do. Recently, we determined the crystal structure of an endo-β-1,4-xylanase (GH11) from mesophilic Talaromyces cellulolyticus, named XylC. Ligand-free XylC exists to two conformations (open and closed forms).

As such, it plays a major role in micro-organisms thriving on plant sources for the degradation of plant matter into usable nutrients. Xylans, the major portion of the hemicellulose of plant cell walls and grasses, are heteropolymers consisting principally of xylose and arabinose. Microbial xylanases with different multiplicities and properties are reported. Abstract An orthorhombic crystal of xylanase II from Trichoderma reesei was grown in the presence of sodium iodide. Crystal structures at atomic resolution were determined at 100 and 293 K. Protein molecules were aligned along a crystallographic twofold screw axis, forming a helically extended polymer-like chain mediated by an iodide ion. Xylanases are hydrolytic enzymes which randomly cleave the β 1,4 backbone of the complex plant cell wall polysaccharide xylan.

*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.

The secondary structure of xylanase II from Trichoderma reesei is lost in an apparent irreversible cooperative process as temperature is increased with a midpoint transition of 58.8 ± 0.1°C. The shift of the spectral centre of mass above 50°C is also apparently cooperative with midpoint transition of 56.3 ± 0.2°C, but the existence of two isofluorescent points in the fluorescence
