Previous structural studies of a number of GH10 xylanases revealed that all GH10 family members have the (β/α) (8)-barrel fold and their catalytic site is conserved. Crystal structure of family 11 xylanase in complex with inhibitor (XIP-I) DOI: 10.2210/pdb1TE1/pdb; Classification: HYDROLASE INHIBITOR/HYDROLASE; Organism(s): Triticum aestivum, Talaromyces funiculosus; Expression System: Talaromyces funiculosus; Mutation(s): No ; Deposited: 2004-05-24 Released: 2004-07-20 Structure–specificity relationships of an intracellular xylanase from Geobacillus stearothermophilus V. 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. Studies of an inactive enzyme–substrate complex will help to elucidate the structural basis of binding and catalysis in the family 2016-08-09 · Recently, we determined the crystal structure of an endo-β-1,4-xylanase (GH11) from mesophilic Talaromyces cellulolyticus, named XylC.

Prepared by dyeing wheat flour arabinoxylan with Remazol Brilliant Blue R dye. Substrate for the assay of endo-1,4-β-D-xylanase. Please note the video above shows the protocol for assay of endo-cellulase using Azo-CM cellulose. The procedure for the assay of endo-1,4-β-xylanase using Azo-Wheat Arabinoxylan (Liquid) is equivalent to this. 2019-06-17 · An extreme halophilic xylanase, designated as XylCMS, was characterized by cloning and expression of the encoding gene from a camel rumen metagenome. XylCMS proved to be a GH11 xylanase with high identity to a hypothetical glycosyl hydrolase from Ruminococcus flavefaciens. XylCMS with a molecular weight of about 47 kDa showed maximum activity at pH 6 and 55 °C.

lan-specific xylanase that The catalytic domain of XynCDBFV, a glycoside hydrolase family 11 (GH11) xylanase from ruminal fungus Neocallimastix patriciarum previously engineered to exhibit higher specific activity and broader pH adaptability, holds great potential in commercial applications. Here, the crystal structures of XynCDBFV and its complex with substrate were determined to 1.27–1.43 Å resolution.

The xylanase folds in an (α/β) 8 barrel (TIM‐barrel), with additional helices and loops arranged at the “top” forming the active site cleft. In its overall shape, the P simplicissimum xylanase structure is similar to other family 10 xylanases, but its active site cleft is much shallower and wider.

Therefore, several aspects of xylan structure remain unclear.

2019-12-16 · Xylanase isolated from Planococcus sp. SL4 was highly active and stable over the neutral and alkaline pH range from 6 to 11, with maximum activity at pH 7 and more than 60% activity at pH 11 . Xylanase purified from Arthrobacter sp. MTCC 5214 was found stable in a narrow pH range of 7.0–8.0 .
