Stereospecific Assignment in Side Chains  
Stereospecific assignments of side chain proton resonances improve the precision and accuracy of NMR-determined protein structures ( 89JACS3997 , 90BIO1689 , 95BIO5201 ). Examples:
  • Stereospecific assignments of methylene protons ( 87JMB611 ), including those o proline rings ( 95JB123-6 )
  • Methyl groups of valine and leucine residues ( 89JACS3997 , 93FEBS177 , 94JMRB62-104 )
  • Homonuclear couplings for all side chain angles, particularly for lysine and arginine residues ( 95JMRB172-107 , 95JMRB297-106 , and 95JMRB189-108
