A new pulse sequence exploiting double- and zero-quantum evolution of two-spin 15N-13C' coherence is proposed for the accurate measurements of 2J(N(i),C alpha(i-1)) coupling constants. Application of the new experiment is presented for 13C,15N-labeled ubiquitin sample. The density functional theory calculations of 2J(N(i),C alpha(i-1)) coupling constants have been performed to study their dependence on both psi(i - 1) and phi(i - 1) angle in model peptides, and the results exhibit a good correlation with experimental data.

Temperature dependence of fast carbonyl backbone dynamics in chicken villin headpiece subdomain
Abstract Temperature-dependence of protein dynamics can provide information on details of the free energy landscape by probing the characteristics of the potential responsible for the fluctuations. We have investigated the temperature-dependence of picosecond to nanosecond backbone dynamics at carbonyl carbon sites in chicken villin headpiece subdomain protein using a combination of three NMR relaxation rates: 13Câ?² longitudinal rate, and two cross-correlated rates involving dipolar and...
