[NMR paper] Tapping into the native Pseudomonas bacterial biofilm structure by high-resolution multidimensional solid-state NMR
Tapping into the native Pseudomonas bacterial biofilm structure by high-resolution multidimensional solid-state NMR
We present a multidimensional magic-angle spinning (MAS) solid-state NMR (ssNMR) study to characterize native Pseudomonas fluorescens colony biofilms at natural abundance without isotope-labelling. By using a high-resolution INEPT-based 2D ¹H-^(13)C ssNMR spectrum and thorough peak deconvolution at the 1D ssNMR spectra, approximately 80/134 (in 1D/2D) distinct biofilm chemical sites were identified. We compared CP and INEPT ^(13)C ssNMR spectra to differentiate signals...

Membrane proteins in their native habitat as seen by solid-state NMR spectroscopy
Membrane proteins in their native habitat as seen by solid-state NMR spectroscopy
Abstract
Membrane proteins play many critical roles in cells, mediating flow of material and information across cell membranes. They have evolved to perform these functions in the environment of a cell membrane, whose physicochemical properties are often different from those of common cell membrane mimetics used for structure determination. As a result, membrane proteins are difficult to study by traditional methods of structural biology, and they are significantly underrepresented in the protein structure...

Abstract
Unlike water soluble proteins, the structures of helicaltransmembrane proteins depend on a very complex environment. These proteins sit in the midst of dramatic electrical and chemical gradients and are often subject to variations in the lateral pressure profile, order parameters, dielectric...
