Enzyme Activities of Recombinant GNA1 and GNA1G68S Proteins.
(A) Time-course analysis of CoA production catalyzed by the GNA activity of GNA1 and GNA1G68S at 18 and 28°C.
(B) Effect of incubation at 18 or 28°C for an extended period of time on the GNA activity of GNA1 or GNA1G68S. The enzyme activities were measured at 28°C after incubation for the indicated periods. Vertical bars represent se values for three measurements.
