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.

First glycoside hydrolase family 2 enzymes from Thermus antranikianii and Thermus brockianus with β-glucosidase activity

Frontiers in Bioengineering and Biotechnology, 2015
Two genes tagh2 and tbgh2 coding for enzymes with hydrolytic activity towards esculin were identified from the extreme thermophilic, aerobic bacteria Thermus antranikianii (Ta) and T. brockianus (Tb). Shortened conserved domains predicted a membership of

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.

Acarbose impairs gut Bacteroides growth by targeting intracellular glucosidases

mBio
Acarbose is a type 2 diabetes medicine that prevents dietary starch breakdown into glucose by inhibiting host amylase and glucosidase enzymes. Numerous gut species in the Bacteroides genus enzymatically break down starch and change in relative abundance ...

Genomic variation drives plant flavor diversification

Journal of Integrative Plant Biology, EarlyView.
This review explains how genomic variation shapes plant flavor by altering the biosynthetic and regulatory pathways of key attributes like sweetness, acidity, bitterness, piquancy, astringency, and aroma. It also discusses how multi‐omics, AI‐assisted breeding, and gene editing can translate this knowledge into plants with improved flavor, nutrition ...

Functional metagenomics identifies an exosialidase with an inverting catalytic mechanism that defines a new glycoside hydrolase family (GH156)

Journal of Biological Chemistry, 2018
Exosialidases are glycoside hydrolases that remove a single terminal sialic acid residue from oligosaccharides. They are widely distributed in biology, having been found in prokaryotes, eukaryotes, and certain viruses.
