The vicinal amide proton-C alpha proton spin-spin coupling constants, JHN alpha, in the globular protein basic pancreatic trypsin inhibitor (BPTI) have been measured using phase-sensitive correlated spectroscopy at high digital resolution. In conjunction with the crystal structure of BPTI, these data were used to calibrate the correlation between 3JHN alpha and the dihedral angle phi. The resulting "BPTI curve" is 3JHN alpha = 6.4 cos2 theta - 1.4 cos theta + 1.9 (theta = [phi - 60 degrees]). It is further shown that measurement of the spin-spin couplings 3JHN alpha presents an independent, reliable method for identification of the location of helical structure in the amino acid sequence of proteins.
