Quantitative J-correlation and triple-resonance ECOSY-type experiments are used to unambiguously establish the presence of four-bond sequential HN-H ~ J-couplings in the protein staphylococcal nuclease. Substantially negative 4JHc~HN values, ranging from -0.8 to -2.3 Hz, are observed when the ~ ang
A modification to the recently proposed α/β-HN(CO)CA-J TROSY pulse sequence (P. Permi et al., J. Magn. Reson. 146, 255-259 (2000)) makes it possible to determine 3 J(H α i , N i+1 ) coupling constants from a single E.COSY-type cross-peak pattern rather than from two 1 H α spin-state-edited subspectr
