, 2022 Retaining glycoside hydrolases are enzymes that catalyse the breakdown down of glycans through hydrolysis. Due to the double-replacement mechanism of the retaining glycoside hydrolases (GHs), which form an intermediate with part of the glycan covalently ...

FoodsAlthough enormous efforts have been made to prepare tasty and soluble steviol glycosides (SGs), the structure–property relationship of SGs still remains unclear, neither in experiment fact nor in the mechanism, such as the influence of linkage type and ...

Transglycosylation of Thiamin by Fungal β-N-Acetylhexosaminidases [PDF]
Bioscience, Biotechnology, and Biochemistry, 1998 A new thiamin glycoside, e.g., thiamin β-D-2-deoxy-2-acetamidoglucopyranoside was prepared by transglycosylation by β-N-acetylhexosaminidase from Aspergillus oryzae and characterized spectrally. Series of other fungal β-N-acetyl-hexosaminidases from A. awamori, A. tamari, A. terreus, and Penicillium oxalicum were shown to be able to synthesize the same

The Formation of Covalent Linkages in Lignocellulosic Biomass via the Oxocarbenium Intermediate
ChemPhysChem, Volume 27, Issue 4, 25 February 2026.Density functional theory models show that the hydrated and acidic hemicellulose matrix in lignocellulosic biomass can generate oxocarbenium ions. These reactive intermediates can participate in the stable formation of glycosidic lignin‐carbohydrate covalent linkages, promoting recalcitrance in plant biomass.

Advancements in the Engineering Modification of Sucrose Phosphorylase
CrystalsSucrose phosphorylase (SPase) is a member of the glycoside hydrolase family 13, catalyzing the reversible phosphorolysis of sucrose to produce α–glucose–1–phosphate and exhibiting transglycosylation activity toward multiple substrates. Its wide substrate

A structural perspective on α‐glucan catabolism in oxygenic phototrophs
The Plant Journal, Volume 125, Issue 3, February 2026.SUMMARY Starch and glycogen are the main α‐glucan storage polymers in oxygenic photoautotrophs, ensuring metabolic continuity during day/night cycles and environmental stress. Their mobilization requires a suite of catabolic enzymes whose activities are tightly regulated to balance carbon storage with energy demands.

Advanced Synthesis &Catalysis, Volume 368, Issue 1, January 2026.Al‐Hilfi et al. present a biocatalytic strategy for synthesizing 5‐methyl‐5,6‐dihydrothymidine (5‐MDHT), a sensitive MRI contrast agent. The study demonstrates that recombinant enzyme catalysis offers an efficient, sustainable, and eco‐friendly alternative to traditional chemical synthesis for producing clinically relevant imaging probes.
