Default NMR solution structure determination of large RNA-protein complexes.

NMR solution structure determination of large RNA-protein complexes.

NMR solution structure determination of large RNA-protein complexes.

Prog Nucl Magn Reson Spectrosc. 2016 Nov;97:57-81

Authors: Yadav DK, Lukavsky PJ

Abstract
Structure determination of RNA-protein complexes is essential for our understanding of the multiple layers of RNA-mediated posttranscriptional regulation of gene expression. Over the past 20years, NMR spectroscopy became a key tool for structural studies of RNA-protein interactions. Here, we review the progress being made in NMR structure determination of large ribonucleoprotein assemblies. We discuss approaches for the design of RNA-protein complexes for NMR structural studies, established and emerging isotope and segmental labeling schemes suitable for large RNPs and how to gain distance restraints from NOEs, PREs and EPR and orientational information from RDCs and SAXS/SANS in such systems. The new combination of NMR measurements with MD simulations and its potential will also be discussed. Application and combination of these various methods for structure determination of large RNPs will be illustrated with three large RNA-protein complexes (>40kDa) and other interesting complexes determined in the past six and a half years.

Fast methionine-based solution structure determination of calcium-calmodulin complexes
Fast methionine-based solution structure determination of calcium-calmodulin complexes Abstract Here we present a novel NMR method for the structure determination of calcium-calmodulin (Ca2+-CaM)-peptide complexes from a limited set of experimental restraints. A comparison of solved CaM-peptide structures reveals invariability in CaMÔ??s backbone conformation and a structural plasticity in CaMÔ??s domain orientation enabled by a flexible linker. Knowing this, the collection and analysis of an extensive set of NOESY spectra is redundant. Although RDCs can define CaM domain orientation in...

Structure Determination of Protein Complexes by NMR
Structure Determination of Protein Complexes by NMR D. Nietlispach, H.R. Mott, K.M. Stott, P.R. Nielsen, A. Thiru & E.D. Laue The Department of Biochemistry, University of Cambridge Introduction As the structures of more proteins and domains are solved by structural genomics projects, the future of structural biology will be oriented more toward the study of macromolecular complexes. Since so many biological processes are mediated by interactions between proteins, it is important to study them at a molecular level. The study of protein-protein interactions also has applications in a...
