Enzyme systems for fragmentation of the rhamnogalacturonan sites main chains in plant tissue protopectin complex

open access: yesПищевые системы, 2023
Special features of the protopectin complex structure of plant tissue suggest the necessity of performing point destruction of certain glycoside bonds in the structure of rhamnogalacturonan polymer chains for industrial production of pectin. These chains

Discovery of glycoside hydrolase enzymes in an avicel-adapted forest soil fungal community by a metatranscriptomic approach. [PDF]

open access: yesPLoS ONE, 2013
To discover the structural and functional novel glycoside hydrolase enzymes from soil fungal communities that decompose cellulosic biomass, transcripts of functional genes in a forest soil were analyzed.

A New Subfamily of Glycoside Hydrolase Family 30 with Strict Xylobiohydrolase Function

open access: yesFrontiers in Molecular Biosciences, 2021
The Acetivibrioclariflavus (basonym: Clostridium clariflavum) glycoside hydrolase family 30 cellulosomal protein encoded by the Clocl_1795 gene was highly represented during growth on cellulosic substrates.

A Case Study of the Glycoside Hydrolase Enzyme Mechanism Using an Automated QM-Cluster Model Building Toolkit

open access: yesFrontiers in Chemistry, 2022
Glycoside hydrolase enzymes are important for hydrolyzing the β-1,4 glycosidic bond in polysaccharides for deconstruction of carbohydrates. The two-step retaining reaction mechanism of Glycoside Hydrolase Family 7 (GH7) was explored with different sized ...

High resolution crystal structure of the Endo-N-acetyl-beta-D-glucosaminidase responsible for the deglycosylation of hypocrea jecorina cellulases [PDF]

open access: yes, 2012
Endo-N-acetyl-beta-D-glucosaminidases (ENGases) hydrolyze the glycosidic linkage between the two N-acetylglucosamine units that make up the chitobiose core of N-glycans. The endo-N-acetyl-beta-D-glucosaminidases classified into glycoside hydrolase family

Crystal structure of a homotrimeric verrucomicrobial exo-β-1,4-mannosidase active in the hindgut of the wood-feeding termite Reticulitermes flavipes

open access: yesJournal of Structural Biology: X, 2021
The termite Reticulitermes flavipes causes extensive damage due to the high efficiency and broad specificity of the ligno- and hemicellulolytic enzyme systems produced by its symbionts. Thus, the R.

Functional metagenomics reveals novel β-galactosidases not predictable from gene sequences. [PDF]

open access: yesPLoS ONE, 2017
The techniques of metagenomics have allowed researchers to access the genomic potential of uncultivated microbes, but there remain significant barriers to determination of gene function based on DNA sequence alone.

Increase of intestinal bacterial sialidase activity exacerbates acute colitis in mice

open access: yesFrontiers in Molecular Biosciences, 2022
The availability of endogenous and dietary carbohydrates in the gastrointestinal tract influences the composition of the gut microbiota. Carbohydrate foraging requires the action of bacterially-encoded glycoside hydrolases, which release mono- and ...

Annotation and comparative analysis of the glycoside hydrolase genes in Brachypodium distachyon

open access: yesBMC Genomics, 2010
Background Glycoside hydrolases cleave the bond between a carbohydrate and another carbohydrate, a protein, lipid or other moiety. Genes encoding glycoside hydrolases are found in a wide range of organisms, from archea to animals, and are relatively ...
