Identification of helix capping and beta-turn motifs from NMR chemical shifts
Identification of helix capping and beta-turn motifs from NMR chemical shifts
Abstract We present an empirical method for identification of distinct structural motifs in proteins on the basis of experimentally determined backbone and 13Cβ chemical shifts. Elements identified include the N-terminal and C-terminal helix capping motifs and five types of beta-turns: I, II, I', II' and VIII. Using a database of proteins of known structure, the NMR chemical shifts, together with the PDB-extracted amino acid preference of the helix capping and β-turn motifs are used as input data for...

Two-dimensional concurrent HMQC-COSY as an approach for small molecule chemical shift assignment and compound identification
Two-dimensional concurrent HMQC-COSY as an approach for small molecule chemical shift assignment and compound identification
Abstract Chemical shift assignment is the first step toward the structure elucidation of natural products and other chemical compounds. We propose here the use of 2D concurrent HMQC-COSY as an experiment for rapid chemical shift assignment of small molecules. This experiment provides well-dispersed 1Hâ??13C peak patterns that are distinctive for different functional groups plus 1Hâ??1H COSY connectivities that serve to identify adjacent groups. The COSY diagonal...
