Biocatalysis and Biotransformation, 2006
The glycoside hydrolases are a large group of enzymes that can be grouped into two major mechanistic classes based upon the stereochemical outcome of catalysis: retention and inversion of sugar anomeric configuration. Both mechanisms involve nucleophilic displacement at the anomeric center, and both proceed via positively charged oxocarbenium ion-like ...

Strategies for tailoring pH performances of glycoside hydrolases
Critical Reviews in Biotechnology, 2021Glycoside hydrolases (GHs) exhibit high activity and stability under harsh conditions, such as high temperatures and extreme pHs, given their wide use in industrial biotechnology. However, strategies for improving the acidophilic and alkalophilic adaptations of GHs are poorly summarized due to the complexity of the mechanisms of these adaptations. This

Bioprospecting Metagenomics for New Glycoside Hydrolases
2012To efficiently deconstruct recalcitrant plant biomass to fermentable sugars in industrial processes, biocatalysts of higher performance and lower cost are required. The genetic diversity found in the metagenomes of natural microbial biomass decay communities may harbor such enzymes.

Formation of glycoside-hydrolases by oral streptococci
Archives of Oral Biology, 1973Abstract The formation of glycoside-hydrolases by oral streptococci grown in different substrates under different conditions was investigated. A proteose peptone medium was superior to brain-heart infusion broth and Todd-Hewitt broth for production of all enzymes.

Glycoside hydrolases in the biodegradation of lignocellulosic biomass
3 Biotech, 2023Lignocellulose is a plentiful and intricate biomass substance made up of cellulose, hemicellulose, and lignin. Cellulose and hemicellulose are polysaccharides characterized by different compositions and degrees of polymerization. As renewable resources, their applications are eco-friendly and can help reduce reliance on petrochemical resources.

Physiological roles of plant glycoside hydrolases
Planta, 2007The functions of plant glycoside hydrolases and transglycosidases have been studied using different biochemical and molecular genetic approaches. These enzymes are involved in the metabolism of various carbohydrates containing compounds present in the plant tissues. The structural and functional diversity of the carbohydrates implies a vast spectrum of

Modeling catalytic reaction mechanisms in glycoside hydrolases
Current Opinion in Chemical Biology, 2019Modeling catalysis in carbohydrate-active enzymes is a daunting challenge because of the high flexibility and diversity of both enzymes and carbohydrates. Glycoside hydrolases (GHs) are an illustrative example, where conformational changes and subtle interactions have been shown to be critical for catalysis.

Phylogenetic analysis of family 6 glycoside hydrolases
Biopolymers, 2005AbstractMultiple sequence alignment separates members of glycoside hydrolase Family 6 into eight subfamilies: one of mainly actinobacterial endoglucanases (EGs), one of ascomycotal EGs, one of chytridiomycotal EGs and cellobiohydrolases (CBHs), one of actinobacterial and proteobacterial CBHs, one of chytridiomycotal CBHs, two of ascomycotal CBHs, and ...

Insight into the Thermophilic Mechanism of a Glycoside Hydrolase Family 5 β-Mannanase.
Journal of Agricultural and Food Chemistry, 2018To study the molecular basis for thermophilic β-mannanase of glycoside hydrolase family 5, two β-mannanases, TlMan5A and PMan5A, from Talaromyces leycettanus JCM12802 and Penicillium sp. WN1 were used as models.

GLYCOSIDE HYDROLASES IN APLYSIA FASCIATA: ANALYSIS AND APPLICATIONS
Biotechnology and Genetic Engineering Reviews, 2008Glycosylation is considered to be an important reaction for the chemical modification of compounds with useful biological activities. Glycoside hydrolases are biotechnologically attractive enzymes which can be used in synthetic reactions for assembling glycosidic linkages with absolute stereoselectivity at an anomeric centre.
