An Update: Enzymatic Synthesis for Industrial Applications

open access: yesAngewandte Chemie International Edition, Volume 64, Issue 27, July 1, 2025.
Biocatalysis has become a sustainable and cost‐competitive alternative to established chemical synthesis, enabling the enzyme‐based production of not only commodity chemicals but (non‐natural) amino acids, (rare) sugars, as well as synthetic nucleotides.

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

open access: yesMass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

Bottom‐Up Synthesized Glucan Materials: Opportunities from Applied Biocatalysis

open access: yesAdvanced Materials, Volume 36, Issue 27, July 4, 2024.
Linear d‐glucans, simple yet versatile polysaccharides, shape nanostructures crucial for biomaterial development. Shifting from top‐down to bottom‐up synthesis using natural and engineered enzymes provides meticulous control over polymer structures, fostering diversification for macromolecular materials.

A β-(1,2)-Glycosynthase and an Attempted Selection Method for the Directed Evolution of Glycosynthases

open access: yes, 2016
Understanding how enzymes mediate catalysis is a key to their reprogramming for biotechnological applications. The family 3 retaining glycosidase postulated to be involved in erythromycin self-resistance was cloned, recombinantly expressed in Escherichia

The First Glycosynthase Derived from an Inverting Glycoside Hydrolase [PDF]

open access: yesJournal of Biological Chemistry, 2006
Reducing end xylose-releasing exooligoxylanase (Rex, EC 3.2.1.156) is an inverting GH that hydrolyzes xylooligosaccharides (> or = X3) to release X1 at their reducing end. The wild-type enzyme exhibited the Hehre resynthesis hydrolysis mechanism, in which alpha-X2F was hydrolyzed to X2 and HF in the presence of X1 as an acceptor molecule.

A Universal Screening Assay for Glycosynthases: Directed Evolution of Glycosynthase XynB2(E335G) Suggests a General Path to Enhance Activity

open access: yesChemistry & Biology, 2008
Glycosynthases are catalytic mutants of mainly retaining glycoside hydrolases that catalyze the synthesis of oligosaccharides from their corresponding glycosyl-fluoride donors and suitable acceptors. Here we describe the development of a general, high-throughput screening procedure for glycosynthase activity, which is based on the release of ...

Glycosynthase Principle Transformed into Biocatalytic Process Technology: Lacto‑N‑triose II Production with Engineered exo-Hexosaminidase

open access: yes, 2019
Glycosynthases are promising enzyme catalysts for glycoside synthesis. Derived from glycoside hydrolases by mechanistic repurposing of their active site, glycosynthases utilize suitably activated glycosyl donors for glycosylation, yet they are unable to ...
