Bifidobacteria exhibit social behavior through carbohydrate resource sharing in the gut [PDF]

, 2017
Bifidobacteria are common and frequently dominant members of the gut microbiota of many animals, including mammals and insects. Carbohydrates are considered key carbon sources for the gut microbiota, imposing strong selective pressure on the complex ...

A Genomic Catalog of Migratory Microbiomes from Wild Birds across China's Habitats

Advanced Science, EarlyView.
ABSTRACT Migratory birds play an important role in the spread of antimicrobial resistance (AMR); however, gaps in surveillance data from vital regions along migratory flyways across China limit the detection of emergent threats. Here, we assembled 340 metagenomes from 52 bird species covering 11 provincial administrative districts in China, presenting ...

Rhamnogalacturonan lyase reveals a unique three‐domain modular structure for polysaccharide lyase family 4 [PDF]

FEBS Letters, 2004
Rhamnogalacturonan lyase (RG‐lyase) specifically recognizes and cleaves α‐1,4 glycosidic bonds between l‐rhamnose and d‐galacturonic acids in the backbone of rhamnogalacturonan‐I, a major component of the plant cell wall polysaccharide, pectin.

A Novel Bifunctional Endolytic Alginate Lyase with Variable Alginate-Degrading Modes and Versatile Monosaccharide-Producing Properties

Frontiers in Microbiology, 2018
Endo-type alginate lyases usually degrade alginate completely into various size-defined unsaturated oligosaccharide products (≥disaccharides), while exoenzymes primarily produce monosaccharide products including saturated mannuronate (M) and guluronate ...
