Commensal butyrate-producing bacteria belonging to the Firmicutes phylum are abundant in human gut and crucial for maintaining health. Currently, insight is lacking into how they target otherwise indigestible dietary fibers trophic interactions establish with other glycan degraders competitive environment.
β-mannans and xylans are important components of the plant cell wall they acetylated to be protected from degradation by glycoside hydrolases. widely present in human animal diets as fiber leguminous plants thickeners stabilizers processed foods. There many fully characterized acetylxylan esterases (AcXEs); however, enzymes deacetylating mannans less understood. Here we two carbohydrate esterases, Ri CE2 CE17, Firmicute Roseburia intestinalis , which together deacetylate complex...
Non-carbohydrate modifications such as acetylations are widespread in food stuffs well they play important roles diverse biological processes. These meet the gut environment and removed from their carbohydrate substrates by resident microbiota. Among most abundant O-acetylations, contributing to polysaccharides physico-chemical properties viscosity gelling ability, reducing accessibility for glycosyl hydrolases, thus hindering polysaccharide degradation. Of particular note, O-acetylations...
ABSTRACT β-Mannans are hemicelluloses that abundant in modern diets as components seed endosperms and common additives processed food. Currently, the collective understanding of β-mannan saccharification human colon is limited to a few keystone species, which presumably liberate low-molecular-weight mannooligosaccharide fragments become directly available surrounding microbial community. Here we show dominant butyrate-producer gut, Faecalibacterium prausnitzii , able acquire degrade various...
