Three-dimensional triple resonance experiments have become an integral part of virtually every solution NMR study of proteins. The approach relies on uniform isotopic enrichment of proteins with 13C and 15N, and establishes the scalar connectivity pathway between nuclei through the large 1JNH, 1JCH, 1JCC, and 1JCN couplings. The magnetization transfer process takes place through multiple, efficient one-bond magnetization transfer steps, rather than a single step through the smaller and variable 3JHH couplings. The relatively large size and good uniformity of the one-bond couplings allowed the design of efficient magnetization transfer schemes that are effectively uniform across a given protein, nearly...
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 15Nā??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...

Four new and complementary three-dimensional triple-resonance experiments are described for obtaining complete backboneH,C, andN resonance assignments of proteins uniformly enriched withC andN. The new methods all rely onH detection and use multiple magnetization transfers through well-resolved one-bondJcouplings. Therefore, the...

Abstract
Three-dimensional triple resonance experiments have become an integral part of virtually every solution NMR study of proteins. The approach relies on uniform isotopic enrichment of proteins with (13)C and (15)N, and establishes the scalar connectivity pathway between nuclei through the large (1)J(NH), (1)J(CH)(, 1)J(CC), and (1)J(CN)...

We provide quantitative signal to noise data and feasibility study at 900 MHz for 1H-15N-13C triple resonance backbone assignment pulse sequences obtained from a medium sized 2H, 13C, 15N labeled protein slowed down in glycerol-water solution to mimic relaxation and spectroscopic properties of a much larger protein system with...

Triple-resonance solid-state NMR spectroscopy is demonstrated to sequentially assign the 13C' and 15N amide backbone resonances of adjacent residues in an oriented protein sample. The observed 13C' chemical shift frequency provides an orientational constraint complementary to those measured from the 1H and 15N amide...
