Figure 4.

NMR waterLOGSY spectra for a series of standard and modified nucleotide triphosphates with MA3706 protein. Nucleotides screened are (a) adenosine triphosphate, (b) guanosine triphosphate, (c) inosine triphosphate, and (d) xanthosine triphosphate. A control spectrum of MA3706 is shown in (e). Peaks due to nucleotide protons are labeled with an asterisk in each spectrum. The exchangeable amino groups of ATP and GTP are labeled in (a) and (b).
