    Multimodularity of a GH10 Xylanase Found in the Termite Gut Metagenome

    Xylan is the major hemicellulosic polysaccharide in cereals and contributes to the recalcitrance of the plant cell wall toward degradation. Bacteroidetes, one of the main phyla in rumen and human gut microbiota, have been shown to encode polysaccharide utilization loci dedicated to the degradation of xylan. Here, we present the biochemical characterization of a xylanase encoded by a bacteroidetes strain isolated from the...

    A Novel Subfamily of Endo-β-1,4-Glucanases in Glycoside Hydrolase Family 10

    Cellulase and xylanase have been widely used in the textile, pulp and paper, animal feed, and food-processing industries. Exploring novel cellulases and xylanases for biocatalysts continues to be a hot issue. Enzymes derived from the polar seas might have novel hydrolysis patterns, substrate specificities, or extremophilic properties that have great potential for both fundamental research and industrial applications. Here, we identified...

    Glycoside Hydrolase Genes Are Required for Virulence of Agrobacterium tumefaciens on Bryophyllum daigremontiana and Tomato

    A. tumefaciens is used in the construction of genetically engineered plants, as it is able to transfer DNA to plant hosts. Knowledge of the mechanisms of DNA transfer and the genes required will aid in the understanding of this process. Manipulation of glycoside hydrolases may increase transformation and widen the host range of the bacterium....

    Discovery of a Thermostable GH10 Xylanase with Broad Substrate Specificity from the Arctic Mid-Ocean Ridge Vent System

    Hot springs at the sea bottom harbor unique biodiversity and are a promising source of enzymes with interesting properties. We describe the functional characterization of a thermophilic and halophilic multidomain xylanase originating from the Arctic Mid-Ocean Ridge vent system, belonging to the well-studied family 10 of glycosyl hydrolases (GH10). This xylanase, AMOR_GH10A, has a surprisingly wide substrate range and is more active...
