Abstract
A convenient and economical method is described for the site-specific N-15-labelling of the 4-amino group of individual cytidine residues in oligonucleotides. This is applied to a 20 base-pair oligonucleotide c orresponding to the trp operator; this oligonucleotide and its complex with the E. coli trp repressor are studied by NMR, using H-1-N-15 HMQ C and N-15-edited H-1-H-1 NOESY experiments.
