gfsA encodes a novel galactofuranosyltransferase involved in biosynthesis of galactofuranose antigen of O‐glycan in Aspergillus nidulans and Aspergillus fumigatus
This is the first characterization of a fungal β‐galactofuranosyltransferase, which was shown to be involved in Galf antigen biosynthesis of O‐glycans in the Golgi.

A detailed kinetic and chemical mechanism for the unique non-redox reaction of UGM is presented, showing for the first time that NADPH is an effective redox partner of TcUGM and supporting the proposal of the flavin acting as a nucleophile.
Targeting UDP-Galactopyranose Mutases from Eukaryotic Human Pathogens
It has become clear that UGMs from prokaryotic and eukaryotic organisms have different structural and mechanistic features, resulting in differences in oligomeric states, substrate binding, active site flexibility, and interaction with redox partners.

Computer simulations of T. cruzi UGM in the presence or absence of an active site ligand suggest a modular mechanism in which each moiety of the substrate controls the flexibility of a different protein loop and indicate that interactions with the substrate diphosphate moiety are especially important for stabilizing the closed active site.

It was concluded that, depending on the number of secondary amines in the repeat unit, these polymers interact with pDNA via different mechanisms with varying extents of electrostatic interaction and hydrogen bonding, which may affect the ability of trehalose to serve as a deterrent against aggregation in serum conditions and lend insight into the roles of polymer-pDNA binding during the complex transfection process.

Celastrol, a natural quinone methide, was identified as a noncompetitive inhibitor of SidA with a MIC value of 2 μM and docking experiments suggest that celastrol binds across the NADPH and l-Orn pocket.
