Characterization of the Fast Dynamics of Protein Amino Acid Side Chains Using NMR Relaxation in Solution

“…The full relaxation matrix for spin 1 having five independent elements was calculated by Jacobsen and coworkers. 22 In this section, we present a derivation of T 1 , the spin-lattice relaxation time for 2 H. The rest of the relaxation parameters can be derived using similar procedures.…”

“…The new methodology was validated using malate synthase G (MSG), a 82 kDa protein, labeled with 13 CH 2 D at the Ile δ positions. Relaxation properties of all 2 H coherences (Equations 30 -31) with the exception of the double-quantum coherence were measured and found to obey self-consistency relationships 22 . In addition, a pulse sequence for the measurements of 2 H T 2 in isolated 13 CHD 2 groups was presented and applied to [ 13 CHD 2 -Ile δ ] MSG.…”

Recent NMR Studies of Thermotropic Liquid Crystals

“…By applying the Redfield theory [140], the deuterium spin-lattice relaxation times of the Zeeman (T 1Z ) and quadrupolar (T 1Q ) orders, neglecting contributions from the dipolar Hamiltonian, are given by [141,142]:…”

Fast Side-Chain Dynamics: Measurement, Analysis, and Their Role in Protein Function

“…The 2 H nucleus has five independent operators or relaxation modes, with discrete relaxation rates that can linearly combined to describe the density matrix. The equations that describe these five independent relaxation modes are as follows [22]:…”
