Protein backboneN NMR spin relaxation rates are useful in characterizing the protein dynamics and structures. To observe the protein nuclear-spin resonances a pulse sequence has to include a water suppression scheme. There are two commonly employed methods, saturating or dephasing the water spins with pulse field gradients and keeping them unperturbed with flip-back pulses....

Domain cooperativity in multidomain proteins: what can we learn from molecular alignment in anisotropic media?
Abstract Many proteins have modular design with multiple globular domains connected via flexible linkers. As a simple model of such system, we study a tandem construct consisting of two identical SH3 domains and a variable-length Gly/Ser linker. When the linker is short, this construct represents a dumbbell-shaped molecule with limited amount of domainā??domain mobility. Due to its elongated shape, this molecule efficiently aligns in steric alignment media. As the length of...

We present a unified framework to describe nuclear spin relaxation in isotropic and anisotropic solutions for single-domain diffusers. All expressions, diffusion and net spin-relaxation theory are derived ab initio. Complete analytical expressions are provided wherever...
