Molecular recognition of natural and non-natural substrates by cellodextrin phosphorylase from Ruminiclostridium thermocellum investigated by NMR spectroscopy
?-1->4-glucan polysaccharides like cellulose, derivatives and analogues, are attracting attention due to their unique physicochemical properties, as ideal candidates for many different applications in biotechnology. Access to these polysaccharides with a high level of purity at scale is still challenging, and eco-friendly alternatives using enzymes in vitro are highly desirable. One prominent candidate enzyme is cellodextrin phosphorylase (CDP) from Ruminiclostridium thermocellum , which is able...
[NMR paper] Acidity Strength of Solid Catalysts Probed by Hyperpolarized Natural Abundance 17O NMR Spectroscopy
Acidity Strength of Solid Catalysts Probed by Hyperpolarized Natural Abundance 17O NMR Spectroscopy
Observation of Brønsted acid sites: By enhancing the solid-state NMR signals of 17O at natural abundance with dynamic nuclear polarization (DNP), Pruski et al. were able to measure oxygen–proton distances accurately with sub-picometer precision. The results give insight into the Brønsted acidity of a range of solid acid catalysts.
