M. Sadek et al., N-15 DETECTION OF BROAD AMIDE PROTONS IN PARAMAGNETIC PROTEINS, Journal of the Chemical Society, Chemical Communications, (1), 1995, pp. 105-106
Nitrogen-15 detected NMR experiments allow identification of the broad
ened H-1 resonances of amide hydrogens adjacent to paramagnetic centre
s in an electron transfer protein, the 2[Fe(4)S4] ferredoxin from Clos
tridium pasteurianum.
