Figure 5. TcUGM activity with UDP-Galf.

TcUGM was reduced with either 20 mM dithionite (▪), 0.5 mM NADPH(•), or 2.5 mM NADH(▴). Reactions were performed with 200 nM TcUGM incubated with varying concentrations of substrate for 1 min at 37°C. The data were fit to the Michaelis-Menten equation. Summary of data is presented in Table 3.
