Abstract
Disconnections between in vitro responses and those observed in whole cells confound many attempts to design drugs in areas of serious medical need. A method based on 1D (1) H NMR spectroscopy is reported that affords the ability to monitor the hydrolytic decomposition of the carbapenem antibiotic meropenem inside Escherichia coli cells expressing New Delhi metallo-?-lactamase subclass 1 (NDM-1), an emerging antibiotic-resistance threat. Cell-based NMR studies demonstrated that two known NDM-1 inhibitors, L-captopril and ethylenediaminetetraacetic acid (EDTA), inhibit the hydrolysis of meropenem in vivo. NDM-1 activity in cells was also shown to be inhibited by spermine, a porin inhibitor, although in an in vitro assay, the influence of spermine on the activity of isolated NDM-1 protein is minimal. This new approach may have generic utility for monitoring reactions involving diffusible metabolites in other complex biological matrices and whole-cell settings, including mammalian cells.

Watching protein structure at work in living cells using NMR spectroscopy December 2012 Publication year: 2012 Source:Current Opinion in Chemical Biology, Volume 16, Issues 5–6</br> </br> Isotope-assisted multi-dimensional NMR spectroscopy can now be applied to proteins inside living cells. The technique, called in-cell NMR, aims to investigate the structures, interactions and dynamics of proteins under their native conditions, ideally at an atomic resolution. The application has begun with bacterial cells but has now expanded to mammalian cultured cells, such as HeLa...
