Abstract
Recent studies have shown that lysine side-chain NH3 (+) groups are excellent probes for NMR investigations of dynamics involving hydrogen bonds and ion pairs relevant to protein function. However, due to rapid hydrogen exchange, observation of (1)H-(15)N NMR cross peaks from lysine NH3 (+) groups often requires use of a relatively low temperature, which renders difficulty in resonance assignment. Here we present an effective strategy to assign (1)H and (15)N resonances of NH3 (+) groups at low temperatures. This strategy involves two new (1)H/(13)C/(15)N triple-resonance experiments for lysine side chains. Application to a protein-DNA complex is demonstrated.

Quantifying millisecond time-scale exchange in proteins by CPMG relaxation dispersion NMR spectroscopy of side-chain carbonyl groups
Quantifying millisecond time-scale exchange in proteins by CPMG relaxation dispersion NMR spectroscopy of side-chain carbonyl groups
Abstract A new pulse sequence is presented for the measurement of relaxation dispersion profiles quantifying millisecond time-scale exchange dynamics of side-chain carbonyl groups in uniformly 13C labeled proteins. The methodology has been tested using the 87-residue colicin E7 immunity protein, Im7, which is known to fold via a partially structured low populated intermediate that interconverts with the folded, ground state on the millisecond time-scale....
