Conformation of double-stranded polydeoxynucleotides in solution by proton two-dimensional nuclear Overhauser enhancement spectroscopy.
Proton 2D-NOE spectroscopy has been used to investigate the three-dimensional conformations of several sonicated polydeoxynucleotides in solution. The observed pattern of cross peaks indicate that poly(dAdT) . poly(dAdT1 in all salt concentrations studied (up to 6.6M CsF), and poly(dG-m5dC) . poly(dG-m5dC) in low salt (0.1M NaCU are righthanded B-structures. Poly(dG-m5dC) . poly(dG-m5dC) in Mg2...
متن کاملA Two-Dimensional Nuclear Overhauser Enhancement Experiment Using Semiselective Soft Pulses, and Its Applications to Proteins
Suitably shaped soft pulses (1-3) have frequently been used in high-resolution NMR for the purposes of semiselective excitation. They can be employed to obtain onedimensional analogs of two-dimensional sequences (1, 4) and to record 2D spectra with reduced spectral width in the wI dimension (5). This approach also facilitates the recording of 3D NMR spectra in a reasonable measurement time (6, ...
متن کاملThe Exact Nuclear Overhauser Enhancement: Recent Advances.
Although often depicted as rigid structures, proteins are highly dynamic systems, whose motions are essential to their functions. Despite this, it is difficult to investigate protein dynamics due to the rapid timescale at which they sample their conformational space, leading most NMR-determined structures to represent only an averaged snapshot of the dynamic picture. While NMR relaxation measur...
متن کاملPractical and Theoretical Aspects of Three-Dimensional Homonuclear Hartmann-Hahn-Nuclear Overhauser Enhancement Spectroscopy of Proteins
The practical and theoretical aspects of three-dimensional homonuclear HartmannHahn-nuclear Overhauser enhancement spectroscopy ( 3D HOHAHA-NOESY) are presented and illustrated using the protein a, -purothionin as an example. A number of sequences are proposed with frequency selection either in the F, dimension only or in both the F, and the F2 dimensions, and their relative merits are discusse...
متن کاملTwo-dimensional transferred nuclear Overhauser effect spectroscopy (TRNOESY) studies of nucleotide conformations in arginine kinase complexes.
Two-dimensional proton transfer nuclear Overhauser spectroscopy (TRNOESY) studies of the conformations of the adenosine moieties in the nucleotides bound at the active site of the lobster (Homarus americanus) muscle arginine kinase are reported. TRNOESY measurements were made using a sample protocol chosen to minimize contributions from weak non-specific binding of the nucleotides to the observ...
