SummaryA 3D NMR technique is described which correlates the amide proton and nitrogen resonances of an amino acid residue with the Cα chemical shift of its preceding residue. The technique uses a relay mechanism, transferring magnetization from15N to13Cα via the intervening carbonyl nucleus. This method for obtaining sequential connectivity is less sensitive to large line widths than the alternative HNCA experiment. The technique is demonstrated for the protein calmodulin, complexed with a 26…

This work proposes an approach towards sequential assignment of perdeuterated proteins based on long-range 1H/13C Cross Polarization transfers that gives rise to H/N-separated correlations involving Cα, Cβ, and CO chemical shifts of both, intra- and interresidual contacts, and thus connecting adjacent residues independent of transverse relaxation times.

Carbon-carbon and proton-carbon couplings can be used to bridge the aromatic and aliphatic parts of proton spin systems; this avoids possible ambiguities that may result from the use of nuclear Overhauser effects to assign aromatic amino acid signals.
