The above mechanism of structural adaptation for low-temperature activity of intracellular endoxylanase rXynAHJ2 is different from that of GH 10 extracellular low-Temperature-active endxylanases.

Molecular and Biochemical Characterization of a Novel Xylanase from Massilia sp. RBM26 Isolated from the Feces of Rhinopithecus bieti.

This paper is the first to report a xylanase (XynRBM26) belonging to the glycosyl hydrolase family (GH10) from the genus Massilia with salt tolerance, which could maintain 86% activity in 5 M NaCl, and is applicable to high-salt food and seafood processing, as well as other high-Salt environmental biotechnological fields.

Cloning, expression and characterization of a novel cold-active and halophilic xylanase from Zunongwangia profunda

This may be the first report concerning a cold-adapted xylanase from a non-halophilic species that displays the highest activity at a NaCl concentration range from 3 to 5 M and the features of cold activity and salt tolerance suggest the potential application of XynA in the food industry and bioethanol production from marine seaweeds.

Molecular and Biochemical Characterization of a Novel Multidomain Xylanase from Arthrobacter sp. GN16 Isolated from the Feces of Grus nigricollis

A novel glycosyl hydrolase family 10 (GH 10) xylanase (XynAGN16), consisting of five domains, was revealed from the genome sequence of Arthrobacter sp. GN16 isolated from the feces of Grus



Gene cloning, expression and characterization of a new cold-active and salt-tolerant endo-β-1,4-xylanase from marine Glaciecola mesophila KMM 241

XynA is a strict endo-β-1,4-xylanase with a demand of at least four sugar moieties for effective cleavage, suggesting its potential in xylo-oligosaccharides production and may be the first salt-tolerant xylanase reported.

A xylanase-encoding gene, designated xynA19, was cloned from Sphingobacterium sp. TN19—a symbiotic bacterium isolated from the gut of Batocera horsfieldi larvae—and expressed in Escherichia coli BL21

Cloning and enzymatic characterization of a xylanase gene from a soil-derived metagenomic library with an efficient approach

A soil-derived metagenomic library containing 24,000 transformants was constructed with an efficient strategy for cloning xylanase genes and a gene encoding of XynH able to hydrolyze xylan was obtained, revealing that this enzyme is a new member in the family 10 of xylanases.

Molecular cloning and characterization of the novel acidic xylanase XYLD from Bispora sp. MEY-1 that is homologous to family 30 glycosyl hydrolases

The mature protein of XYLD showed high sequence similarity to both glycosyl hydrolase (GH) families 5 and 30 but was more homologous to members of GH 30 based on phylogenetic analysis.

Novel cold-adaptive Penicillium strain FS010 secreting thermo-labile xylanase isolated from Yellow Sea.

A novel cold-adaptive xylanolytic Penicillium strain FS010 was isolated from Yellow sea sediments and secreted the cold-active xylanase (XYL) showing high hydrolytic activities at low temperature and high sensitivity to high temperature.

Cloning and characterization of a cold-active xylanase enzyme from an environmental DNA library

Cloned a xylanase gene (xyn8) from an environmental genomic DNA library and purified enzyme was thermolabile, had an activity temperature optimum of 20°C on native xylan substrate, and retained significant activity at lower temperatures.

Cloning of a Bacillus sp. BP-23 gene encoding a xylanase with high activity against aryl xylosides.

Xylanase B showed high specific activity on aryl xylosides, probably as a result of the transxylosidase activity detected, and xylobiose was not hydrolyzed by the enzyme.

A Novel Family 8 Xylanase, Functional and Physicochemical Characterization*

This novel xylanase, isolated from the Antarctic bacterium Pseudoalteromonas haloplanktis, is not homologous to family 10 or 11 enzymes but has 20–30% identity with family 8 members and NMR analysis shows that this enzyme hydrolyzes with inversion of anomeric configuration, in contrast to other known xylanases which are retaining.

Structure-specificity relationships of an intracellular xylanase from Geobacillus stearothermophilus.

The structure of IXT6 was compared with the highly homologous extracellular xylanase XT6, revealing a number of structural differences between the active sites of the two enzymes, which may account for the significant differences in the substrate specificities of these otherwise very similar enzymes.
