Sequence‐Based and Functional Analysis for the Discovery of N‐Glycan Degrading Glycosidases From the Microbial Metagenome of the Infant Gut

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.

Enhancement of transglycosylation activity of lysozyme by chemical modification. [PDF]

Agricultural and Biological Chemistry, 1989
An attempt to enhance the transglycosylation activity of lysozyme was made by chemical modification. Computer simulation of the lysozyme-catalyzed reaction indicated that inhibition of the sugar residue binding to the binding subsite A caused a significant increase in transglycosylation activity. Therefore, the binary modification of Asp 101 and Trp 62

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

Plant Xyloglucan Xyloglucosyl Transferases and the Cell Wall Structure: Subtle but Significant

Molecules, 2020
Plant xyloglucan xyloglucosyl transferases or xyloglucan endo-transglycosylases (XET; EC 2.4.1.207) catalogued in the glycoside hydrolase family 16 constitute cell wall-modifying enzymes that play a fundamental role in the cell wall expansion and re ...

Improved Transglycosylation by a Xyloglucan-Active α-l-Fucosidase from Fusarium graminearum

Journal of Fungi, 2020
Fusarium graminearum produces an α-l-fucosidase, FgFCO1, which so far appears to be the only known fungal GH29 α-l-fucosidase that catalyzes the release of fucose from fucosylated xyloglucan.

Transglycosylation Action of Amylases

Journal of the Japanese Society of Starch Science, 1973
By using the substrates of defined anomeric form, with very brief incubation to limit mutarotation, evidence has been obtained that the condensations require donor substrates of specific configuration. That is, crystalline glucoamylase from Rh, niveus has been found to catalyze the rapid synthesis of maltose and a slower synthesis of isomaltose ...
