摘要： Enzymatic sulfations of biomolecules catalyzed by 3′-phosphoadenosine-5′-phosphosulfate (PAPS) dependent sulfotransferases are enhanced by coupling the sulfation reaction an enzymatic regeneration of PAPS. The PAPS is enzymatically regenerated from its hydrolysis product 3′,5′-diphosphate (PAP) using recombinant aryl sulfotransferase as the catalyst and aryl sulfate as the substrate. Biomolecules capable of enhanced sulfation by this method include carbohydrates, oligosaccharides, peptides, proteins, flavonoids, and steroids. When enzymatic sulfation and substrate regeneration steps are coupled, the desulfated aryl group produced in the regeneration step has a spectroscopic signature that can be employed for monitoring the progress of the sulfation of the biomolecule.

摘要： Methods for metabolic oligosaccharide engineering that incorporates derivatized alkyne-bearing sugar analogs as “tags” into cellular glycoconjugates are disclosed. Alkynyl derivatized Fuc and alkynyl derivatized ManNAc sugars are incorporated into cellular glycoconjugates. Chemical probes comprising an azide group and a visual or fluorogenic probe and used to label alkyne-derivatized sugar-tagged glycoconjugates are disclosed. Chemical probes bind covalently to the alkynyl group by Cu(I)-catalyzed [3+2] azide-alkyne cycloaddition and are visualized at the cell surface, intracellularly, or in a cellular extract. The labeled glycoconjugate is capable of detection by flow cytometry, SDS-PAGE, Western blot, ELISA, confocal microscopy, and mass spectrometry.

摘要： Moenomycin inhibits bacterial growth by clocking the transglycosylase activity of class A penicillin-binding proteins (PBPs), which are key enzymes in bacterial cell wall synthesis. The binding affinities of moenomycin A with various truncated PBPs were compared showing that the transmembrane domain is important for moenomycin binding. Full-length class-A PBPs from 16 bacterial species were produced, and their binding activities showed a correlation with the antimicrobial activity of moenomycin against Enterococcus faecalis and Staphylococcus aureus. Moreover, a fluorescence anisotropy-based high-throughput assay was developed and used successfully for identification of transglycosylase inhibitors.
