8386636-1	1993	Proton-NMR signals in the downfield region (below approximately 10 ppm) have been shown to provide a useful spectroscopic window to monitor the binding of guanine nucleotides to the active site of GTP/GDP-binding proteins via H-bonds, as specified here by the 21-kDa product of the c-H-ras gene (p21).
