SSNMR of biosilica-entrapped enzymes permits an easy assessment of preservation of native conformation in atomic detail

Abstract

Bioinspired silica coprecipitates of enzymes find a wide range of applications for analysis and catalysis in industrial and academic research. Here we used SSNMR as a proxy for the 3D structure of enzymes trapped in bioinspired silica. We show that it is easy to assess whether the enzymes retain their native conformation in atomic detail. We thus propose SSNMR as a rapid and reliable tool to analyze this kind of samples at high resolution.
