Seasonal and Regional Dietary Heterogeneity Is Associated With Gut Microbiota Differentiation in Przewalski's Gazelle (Procapra przewalskii)

Integrative Zoology, EarlyView.
Seasonal and regional dietary variation in Przewalski's gazelle was linked to coordinated changes in gut microbiota, functional pathways, and fecal metabolites. Winter diets featured Poaceae, Cyperaceae, and Iridaceae, whereas summer diets shifted toward forb families.

Structural and thermodynamic analyses of a novel β‐1,2‐glucan binding mode in the ABC transporter solute‐binding protein Chy400_4166 from Chloroflexus aurantiacus

The FEBS Journal, EarlyView.
Cyclic β‐1,2‐glucan (CβG)‐associated solute‐binding protein of type I ABC transporter was originally identified in Chloroflexus aurantiacus, a phototrophic bacterium. Crystal structures in complex with CβGs revealed unique binding modes that are fundamentally distinct from that of the short β‐1,2‐glucooligosaccharides‐binding protein.

Survey of the genome of opitutus terrae and other organisms for novel carbohydrate-active enzyme specificities [PDF]

Lignocellulose is the major component of the plant cell wall and is a sustainable source of inexpensive abundant biomass. Efficient degradation of the lignocellulosic polysaccharides, cellulose and hemicellulose, is required if the plant cell wall is to ...

Discovery of two β-1,2-mannoside phosphorylases showing different chain-length specificities from Thermoanaerobacter sp. X-514.

PLoS ONE, 2014
We characterized Teth514_1788 and Teth514_1789, belonging to glycoside hydrolase family 130, from Thermoanaerobacter sp. X-514. These two enzymes catalyzed the synthesis of 1,2-β-oligomannan using β-1,2-mannobiose and d-mannose as the optimal acceptors ...

Cryo‐EM structure of GH43 β‐Xylosidase from Enterobacter cloacae provides insights into substrate specificity and the role of an auxiliary domain in enzymatic activity

The FEBS Journal, EarlyView.
Xylan, the second most abundant plant cell wall polysaccharide, is degraded by β‐xylanases and β‐xylosidases. Here, we present the 2.65 Å cryo‐EM structure of Enterobacter cloacae β‐xylosidase (EcXyl43, GH43) and the 2.4 Å X‐ray structure of its inactive F507A mutant.

Additional file 1: Figure S1. of Glycoside hydrolase family 32 is present in Bacillus subtilis phages

, 2015
Sequence alignment of enzymes of the GH32 family from Bacillus phages and close homologs of the GH32 enzyme family. The amino acid sequences were compared to close homologs of the GH32 enzyme family found in bacteria, fungi, plants and animals. Accession numbers of sequence are in {} after species name.

Functional and transcriptomic analyses in Neurospora crassa reveal a crucial role for the N‐glycoprotein deglycosylation process in fungal homeostasis

The FEBS Journal, EarlyView.
In Neurospora crassa, a cytosolic GH18 endo‐β‐n‐acetylglucosaminidase (ENGase) functions as an active deglycosylating enzyme. Deletion of this severely alters tolerance to multiple stress conditions and causes extensive transcriptomic reprogramming, including upregulation of a GH20 exo‐β‐n‐acetylhexosaminidase under ER stress, indicating that N. crassa

Structural insights into xyloglucan recognition by an ABC transporter from a Gram‐positive, thermophilic bacterium

The FEBS Journal, EarlyView.
Athe_2052 is an ABC transporter substrate‐binding protein that recognizes xyloglucan heptasaccharide (XXXG), a soluble breakdown product of plant xyloglucan. The crystal structure of Athe_2052, together with binding assays and computational modeling, shows how XXXG is recognized by this sugar transporter.

Refining and mining the phylogeny of Glycoside Hydrolase Family 74 via structure-function analysis [PDF]

, 2017
Sustained interest in the use of carbohydrates from plant cell walls, coupled with the advancement of high-throughput (meta)genomic sequencing, has led to the discovery of an overwhelming number of predicted carbohydrate-active enzymes (CAZymes) in the ...
