Figure 2. ATP is an essential activator of NAMPT and NAPRT reactions.

Figure 2

NAMPT (A, 15 ng) and NAPRT (B, 20 ng) were incubated with 20 µM [14C]Nam and [14C]NA for 6 and 7 min, respectively, in the presence of 1 µM PRPP and indicated concentrations of ATP. The amounts of NMN (A) and NaMN (B) formed were determined. Data in figures 2 and 3 are representative of at least three experiments.
