Prominent members of the human gut microbiota express endo-acting O-glycanases to initiate mucin breakdown

Nature Communications, 2020
Epithelial cells that line the gut secrete complex glycoproteins that form a mucus layer to protect the gut wall from enteric pathogens. Here, the authors provide a comprehensive characterisation of endo-acting glycoside hydrolases expressed by mucin ...

Snake Gut Microbiota as a Source of Anti‐Inflammatory Probiotics: Isolation and Functional Characterization of Two Novel Strains

Integrative Zoology, EarlyView.
This study assessed the probiotic potential of intestinal microbiomes from five snake species using metagenomics and in vitro isolation, identifying two promising strains (Lactobacillus johnsonii DA0116 and Limosilactobacillus reuteri DA0218) through comprehensive screening.

Discovery of a cryptic aminoacidic triad involved in the temperature adaptation of GH1 enzymes

The FEBS Journal, EarlyView.
Cold‐active enzymes retain high catalytic activity at low temperatures but are characterized by thermal instability, a behavior not fully understood. Comparison between a cold‐active GH1 and its mesophilic counterparts highlights the role of a three‐residue motif (W‐M‐F) in conferring structural stability to a mesophilic GH1.

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.

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.

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

Secretome Analysis of Thermothelomyces thermophilus LMBC 162 Cultivated with Tamarindus indica Seeds Reveals CAZymes for Degradation of Lignocellulosic Biomass

Journal of Fungi
The analysis of the secretome allows us to identify the proteins, especially carbohydrate-active enzymes (CAZymes), secreted by different microorganisms cultivated under different conditions. The CAZymes are divided into five classes containing different

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.
