Transglycosylation reactions catalysed by two β-mannanases [PDF]
Biochemical Journal, 1981 By using [3H]mannobiose as a labelled acceptor, it was possible to demonstrate transfer reactions catalysed by two beta-mannanases, with mannotetraose and mannopentaose as substrates. The enzyme from Streptomyces transfers one mannose unit from the oligosaccharides, whereas the enzyme from fenugreek (Trigonella foenum-graecum) seeds is able to transfer

MicrobiologyOpen, Volume 15, Issue 2, April 2026.This research offers valuable understanding of how N‐glycans are broken down by the gut microbiota of infants, focusing on glycoside hydrolase families GH2, GH20, and GH18. It reveals that the gut microbiota of breastfed infants has a diverse array of genes coding for these enzymes.

Computer‐Based Design to Improve Bacillus thuringiensis Chitinase for Industrial Applications
ChemistryOpen, Volume 15, Issue 4, April 2026.Hotspot‐guided mutagenesis identifies Gly291 as a key catalytic determinant in Bacillus thuringiensis chitinase. Substitution with alanine improves substrate accommodation and lowers the activation barrier by ∼47%, reducing it from 94.66 to 49.83 kcal/mol. Structural integrity is retained while catalytic efficiency is enhanced, demonstrating a rational

Effects of monovalent cations (Na+ and K+) on galacto-oligosaccharides production during lactose hydrolysis by kluyveromyces lactis β-galactosidase [PDF]
, 2014 The influence of cations, Na+ and K+ on the oligosaccharides produced in the process of transglycosylation during the hydrolysis of lactose using β-galactosidase from Kluyveromyces (K.) lactis has been investigated. The enzyme exhibited higher hydrolytic
