Very large residual dipolar couplings from deuterated ubiquitin
Very large residual dipolar couplings from deuterated ubiquitin
Abstract Main-chain 1HNâ??15N residual dipolar couplings (RDCs) ranging from approximately â??200 to 200 Hz have been measured for ubiquitin under strong alignment conditions in Pf1 phage. This represents a ten-fold increase in the degree of alignment over the typical weakly aligned samples. The measurements are made possible by extensive proton-dilution of the sample, achieved by deuteration of the protein with partial back-substitution of labile protons from 25 % H2O / 75 % D2O buffer. The spectral quality is further...

Simultaneous measurement of 1Hâ??15N and Methyl 1Hmâ??13Cm residual dipolar couplings in large proteins
Abstract A two-dimensional TROSY-based SIM-13Cmâ??1Hm/1Hâ??15N NMR experiment for simultaneous measurements of methyl 1 D CH and backbone amide 1 D NH residual dipolar couplings (RDC) in {U-; Ileδ1-; Leu,Val-}-labeled samples of large proteins is described. Significant variation in the alignment tensor of the 82-kDa enzyme Malate synthase G is observed as a function of only slight changes in experimental conditions. The SIM-13Cmâ??1Hm/1Hâ??15N data sets provide convenient means...

The accurate experimental determination of dipolar-coupling constants for one-bond heteronuclear dipolar couplings in solids is a key for the quantification of the amplitudes of motional processes. Averaging of the dipolar coupling reports on motions on time scales up to the inverse of the coupling...

Facile measurement of 1Hâ??15N residual dipolar couplings in larger perdeuterated pro
Abstract We present a simple method, ARTSY, for extracting 1JNH couplings and 1Hâ??15N RDCs from an interleaved set of two-dimensional 1Hâ??15N TROSY-HSQC spectra, based on the principle of quantitative J correlation. The primary advantage of the ARTSY method over other methods is the ability to measure couplings without scaling peak positions or altering the narrow line widths characteristic of TROSY spectra. Accuracy of the method is demonstrated for the model system GB3. Application to the catalytic core domain of HIV integrase, a 36 kDa homodimer with unfavorable spectral...
