Combinatorial triple-selective labeling as a tool to assist membrane protein backbone resonance assignment
Combinatorial triple-selective labeling as a tool to assist membrane protein backbone resonance assignment
Abstract Obtaining NMR assignments for slowly tumbling molecules such as detergent-solubilized membrane proteins is often compromised by low sensitivity as well as spectral overlap. Both problems can be addressed by amino-acid specific isotope labeling in conjunction with 15Nâ??1H correlation experiments. In this work an extended combinatorial selective in vitro labeling scheme is proposed that seeks to reduce the number of samples required for assignment. Including three...

RDC derived protein backbone resonance assignment using fragment assembly
Abstract Experimental residual dipolar couplings (RDCs) in combination with structural models have the potential for accelerating the protein backbone resonance assignment process because RDCs can be measured accurately and interpreted quantitatively. However, this application has been limited due to the need for very high-resolution structural templates. Here, we introduce a new approach to resonance assignment based on optimal agreement between the experimental and calculated RDCs from a structural template that...

J Magn Reson. 2001 May;150(1):100-4
Authors: Meissner A, Sørensen OW
The conventional HNCA pulse sequence suffers from the ambiguity that it cannot distinguish inter- and intraresidue correlations because the one-bond and two-bond J(NC(alpha)) coupling constants are of similar magnitude. This paper presents a novel pulse sequence, sequential HNCA, that leads to a spectrum exhibiting...
