Solid State NMR Spectroscopy for Biopolymers

 


Part I: Principles:


Solid state NMR approach: CP-MAS and DD-MAS NMR.- Quadrupolar nuclei.- Brief outline of NMR parameters: Chemical shifts.- Relaxation parameters.- Dynamics-dependent suppression of peaks.- Multinuclear approaches: 31P NMR.- 2H NMR.- 17O NMR.- Experimental strategies: Isotope enrichment (labeling).- Assignment of peaks.- Ultra high-field and ultra high-speed MAS NMR spectroscopy.- NMR constraints for structural determination: Orientational constraint.- Interatomic distance.- Torsion angles.- Conformation-dependent 13C chemical shifts.- Dynamics: Fast motions with motional frequency >106 Hz.- Intermediate or slow motions with frequency between 106 and 103 Hz.- Very slow motions with frequency < 103 Hz.





Part II: Applications:


Hydrogen bonded systems: Hydrogen bond shifts.- 2H quadrupolar coupling constant.- Fibrous proteins: Collagen fibrils.- Elastin.- Cerial proteins.- Silk fibroin.- Keratin.- Bacteriophage coat protein.- Polysaccharides: Distinction of polymorphs.- Network structure, dynamics and gelation mechanism.- Polypeptides as new materials: Liquid crystalline polypeptides.- Blend system.- Globular proteins: (Almost) complete assignment of 13C NMR spectra of globular proteins.- 3D structure: alpha-spectrin SH3 domain.- Ligand-binding to globular protein.- Membrane protein I: dynamic picture: Bacteriorhodopsin.- Phoborhodopsin and its cognitive transducer.- Diacylgycerol kinase.- Membrane proteins II: 3D structure: 3D structure of mechanically aligned membrane proteins.- Secondary structure based on distance constraints.- Biologically active membrane-associated peptides: Channel-forming peptides.- Antimicrobial peptides.- Opioid peptides.- Fusion peptides.- Membrane model system.- Amyloid and related biomolecules: Amyloid beta-peptide.- Calcitonin (CT).
