Front Bioeng Biotechnol. 2015 Oct 27;3:165. doi: 10.3389/fbioe.2015.00165. eCollection 2015.

Chemically synthesized nanostructure-initiator mass spectrometry (NIMS) probes derivatized with tetrasaccharides were used to study the reactivity of representative Clostridium thermocellum β-glucosidase, endoglucanases, and cellobiohydrolase. Diagnostic patterns for reactions of these different classes of enzymes were observed. Results show sequential...

BACKGROUND: The bioconversion of lignocellulosic biomass in various industrial processes, such as the production of biofuels, requires the degradation of hemicellulose. RESULTS: To reveal the hemicellulose-degrading potential of 50 glycoside hydrolases, they were recombinantly produced and characterised. 46 of...

The structure and function of the microbiome inhabiting the rumen are, amongst other factors, mainly shaped by the animal's feed intake. Describing the influence of different diets on the inherent community arrangement and associated metabolic activities of the most...

Impaired coordination of nucleophile and increased hydrophobicity in the +1 subsite shift levansucrase activity towards transfructosylation.

Glycobiology

Ortiz-Soto ME, Possiel C, Görl J, Vogel A, Schmiedel R, Seibel J.

Glycobiology. 2017 Aug 01;27(8):755-765. doi: 10.1093/glycob/cwx050.

Bacterial levansucrases produce β(2,6)-linked levan-type polysaccharides using sucrose or sucrose analogs as donor/acceptor substrates. However, the dominant reaction of Bacillus megaterium levansucrase (Bm-LS) is hydrolysis. Single domain levansucrases from Gram-positive bacteria display a wide substrate-binding pocket with open access...

FiberGrowth Pipeline: A Framework Toward Predicting Fiber-Specific Growth From Human Gut Bacteroidetes Genomes.

Frontiers in microbiology

Front Microbiol. 2021 Oct 06;12:632567. doi: 10.3389/fmicb.2021.632567. eCollection 2021.

Dietary fibers impact gut colonic health, through the production of short-chain fatty acids. A low-fiber diet has been linked to lower bacterial diversity, obesity, type 2 diabetes, and promotion of mucosal pathogens. Glycoside hydrolases (GHs) are important enzymes involved...

Glycoside hydrolases (GHs) are essential for plant biomass deconstruction. GH11 family consist of endo-β-1,4-xylanases which hydrolyze xylan, the second most abundant cell wall biopolymer after cellulose, into small bioavailable oligomers. Structural requirements for enzymatic mechanism of xylan hydrolysis is...

Bacterial biofilms account for up to 80% of all community-acquired infections for which bacterial eradication is currently not achievable using conventional antimicrobial treatments. The protective matrix that engulfs biofilm-associated bacteria frequently renders antibiotics ineffective. Glycoside hydrolases are a class...

Biotechnol Biofuels. 2012 Jul 28;5(1):54. doi: 10.1186/1754-6834-5-54.

BACKGROUND: Thermophilic fungi have attracted increased interest for their ability to secrete enzymes that deconstruct biomass at high temperatures. However, development of thermophilic fungi as enzyme producers for biomass deconstruction has not been thoroughly investigated. Comparing the enzymatic activities...
