Determining isoleucine side-chain rotamer-sampling in proteins from (13)C chemical shift

Chemical shifts are often the only nuclear magnetic resonance parameter that can be obtained for challenging macromolecular systems. Here we present a framework to derive the conformational sampling of isoleucine side chains from (13)C chemical shifts and demonstrate that side-chain conformations in...

Sumario:Chemical shifts are often the only nuclear magnetic resonance parameter that can be obtained for challenging macromolecular systems. Here we present a framework to derive the conformational sampling of isoleucine side chains from (13)C chemical shifts and demonstrate that side-chain conformations in a low-populated folding intermediate can be determined.
