Oral PHGG ameliorates atopic dermatitis‐like dermatitis with concurrent modulation of colonic IgA and cecal microbiota: implications for the gut–skin axis

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Atopic dermatitis (AD) is increasingly recognized as a systemic inflammatory disorder linked to intestinal immune and microbiome dysregulation. However, whether dietary galactomannan fibers can mitigate AD through coordinated modulation of the gut–skin axis remains unexplored.

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

open access: yesThe 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.
