NMR resonance assignment of selectively labeled proteins by the use of paramagnetic l

NMR resonance assignment of selectively labeled proteins by the use of paramagnetic ligands.

Selective isotopic labeling of larger proteins greatly simplifies protein NMR spectra and reduces signal overlap, but selectively labeled proteins cannot be easily assigned since the sequential assignment method is not applicable. Here we describe a strategy for resonance assignment in selectively labeled proteins. Our approach involves a spin-labeled analog of a ligand of which the three-dimensional structure in complex with the target protein is known. Other methods for introduction of the spin label are possible. The paramagnetic center causes faster relaxation of all neighboring nuclei in a distance-dependent manner. Measurement of this effect allows to deduce distances between isotopically labeled residues and the paramagnetic center which can be used for resonance assignment. The method is demonstrated for the catalytic domain of Abl kinase in complex with the inhibitor, STI571.

Multidimensional oriented solid-state NMR experiments enable the sequential assignment of uniformly 15N labeled integral membrane proteins in magnetically aligned lipid bilayers Multidimensional oriented solid-state NMR experiments enable the sequential assignment of uniformly 15N labeled integral membrane proteins in magnetically aligned lipid bilayers Abstract Oriented solid-state NMR is the most direct methodology to obtain the orientation of membrane proteins with respect to the lipid bilayer. The method consists of measuring 1H-15N dipolar couplings (DC) and 15N anisotropic chemical shifts (CSA) for membrane proteins that are uniformly aligned with respect to the membrane bilayer. A significant advantage of this approach is that tilt and azimuthal...	nmrlearner	Journal club	0	10-10-2011 06:27 AM
Automated sequence- and stereo-specific assignment of methyl-labeled proteins by paramagnetic relaxation and methylâ??methyl nuclear overhauser enhancement spectroscopy Automated sequence- and stereo-specific assignment of methyl-labeled proteins by paramagnetic relaxation and methylâ??methyl nuclear overhauser enhancement spectroscopy Abstract Methyl-transverse relaxation optimized spectroscopy is rapidly becoming the preferred NMR technique for probing structure and dynamics of very large proteins up to ~1 MDa in molecular size. Data interpretation, however, necessitates assignment of methyl groups which still presents a very challenging and time-consuming process. Here we demonstrate that, in combination with a known 3D structure, paramagnetic...	nmrlearner	Journal club	0	09-26-2011 06:42 AM
A general Monte Carlo/simulated annealing algorithm for resonance assignment in NMR of uniformly labeled biopolymers A general Monte Carlo/simulated annealing algorithm for resonance assignment in NMR of uniformly labeled biopolymers Abstract We describe a general computational approach to site-specific resonance assignments in multidimensional NMR studies of uniformly 15N,13C-labeled biopolymers, based on a simple Monte Carlo/simulated annealing (MCSA) algorithm contained in the program MCASSIGN2. Input to MCASSIGN2 includes lists of multidimensional signals in the NMR spectra with their possible residue-type assignments (which need not be unique), the biopolymer sequence, and a table that describes...	nmrlearner	Journal club	0	06-30-2011 05:01 AM

An intraresidual i(HCA)CO(CA)NH experiment for the assignment of main-chain resonances in 15N, 13C labeled proteins An intraresidual i(HCA)CO(CA)NH experiment for the assignment of main-chain resonances in 15N, 13C labeled proteins Abstract An improved pulse sequence, intraresidual i(HCA)CO(CA)NH, is described for establishing solely 13Câ?²(i), 15N(i), 1HN(i) connectivities in uniformly 15N/13C-labeled proteins. In comparison to the â??out-and-backâ?? style intra-HN(CA)CO experiment, the new pulse sequence offers at least two-fold higher experimental resolution in the 13Câ?² dimension and on average 1.6 times higher sensitivity especially for residues in Î±-helices. Performance of the new experiment...	nmrlearner	Journal club	0	01-09-2011 12:46 PM
