Figure 5. Magnetic field dependence of substrate and cofactor 31P R1 in D219A•GMP•NADP+ and D219A•IMP•NADP+ complexes.

Figure 5.

Samples (D219A•GMP•NADP+ in red and D219A•IMP•NADP+ in blue) are in 75 mM Tris-HCl, pH 7.8, 100 mM KCl, 1 mM DTT and 0.5 mM EDTA: (A) substrate monophosphate, (B) cofactor monophosphate, and (C) cofactor diphosphates. Error bars are described in Figure 3.
