Modulation of the Activity and Regioselectivity of a Glycosidase: Development of a Convenient Tool for the Synthesis of Specific Disaccharides

open access: yesMolecules, 2021
The synthesis of disaccharides, particularly those containing hexofuranoside rings, requires a large number of steps by classical chemical means. The use of glycosidases can be an alternative to limit the number of steps, as they catalyze the formation ...

TLC analysis of FOS from transglycosylation reactions.

open access: yes, 2014
The transglycosylation reactions were catalyzed by native and recombinant BfrAs incubated with 33% sucrose at optimal reaction condition for 5 h. The FOS were separated by Bio-Gel P2 column.

Transglycosylation Activity ofDictyoglomus thermophilumAmylase A

open access: yesBioscience, Biotechnology, and Biochemistry, 2004
Amylase A from Dictyoglomus thermophilum is a thermophilic enzyme and has about 40% identity with 4-alpha-glucanotransferase (GTase) from Thermococcus litoralis, and both of these enzymes belong to family 57 glycosyl hydrolase. Since the transglycosylation activity of T.

Recombinant expression, purification and characterization of human hyaluronidases

open access: yes, 2007
Hyaluronidases and their substrate, hyaluronic acid, are known to play a role in signal transduction events directly correlated with tumor growth and cell migration. Yet correlations with disease progression are controversial due to scarce information on

Screening Systems for Detecting Inhibitors of Cell Wall Transglycosylation in Enterococcus.Cell Wall Transglycosylation Inhibitors in Enterococcus.

open access: yesThe Journal of Antibiotics, 1998
We devised two screening systems to detect cell wall transglycosylation inhibitors. One screen utilizes a mutant of Enterococcus faecalis strain A256 that is dependent on vancomycin or moenomycin for growth. In the absence of transglycosylation inhibitors the strain fails to grow, while in the presence of inhibitors, cells are rescued.

Exploring Diverse Glycone Preferences of Aspergillus rutinosidases

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
Rutinosidases from Aspergillus niger (AnRut) and A. oryzae (AoRut) catalyze hydrolysis and transglycosylation with non‐natural glycosides as donors, enabling glycosylation of alcoholic and phenolic acceptors. AnRut exhibits broad glycone promiscuity, while AoRut has a narrower substrate scope.

Comprehensive and Comparative Transcriptional Profiling of the Cell Wall Stress Response in Bacillus subtilis

open access: yesMolecular Microbiology, Volume 125, Issue 6, Page 506-545, June 2026.
Transcriptional profiling of the primary cell envelope stress response (CESR) of Bacillus subtilis exposed to a range of cell wall‐targeting antimicrobials, combining RNAseq and high‐resolution tiling arrays. We revealed the complexity of the CESR, the contribution of extracytoplasmic function sigma factors (ECFs) and two‐component signal transduction ...
