Proteins and enzymes generally achieve their functions by creating well-defined 3D architectures that pre-organize reactive functionalities. Mimicking this approach to supramolecular pre-organization is leading to the development of highly versatile artificial chemical environments, including new biomaterials, medicines, artificial enzymes, and enzyme-like catalysts. The use of ?-turn and ?-helical motifs is one approach that enables the precise placement of reactive functional groups to enable...

Structure-based protein NMR assignments using native structural ensembles
Mehmet Serkan Apaydın, Vincent Conitzer and Bruce Randall Donald
Journal of Biomolecular NMR; 2008; 40(4); pp 263-276
Abstract:
An important step in NMR protein structure determination is the assignment of resonances and NOEs to corresponding nuclei. Structure-based assignment (SBA) uses a model structure (“template”) for the target protein to expedite this process. Nuclear vector replacement (NVR) is an SBA framework that combines multiple sources of NMR data (chemical shifts, RDCs, sparse NOEs, amide exchange...
