Kinetic parameters for UDP-Araf transport into proteoliposomes

Parameter UAfT1 UAfT2 UAfT3 UAfT4 AT3G17430 AT1G48230
KM (µM) 10 (1) 10 (1) 10 (2) 7 (1) Ambiguous Ambiguous
Vmax (nM s−1) 11 (0) 8 (0) 2 (0) 8 (0) N.D. N.D.
kcat (s−1) 4 3 3 1 N.D. N.D.

For each transporter, eight data points with varying substrate concentrations (0.5–100 µM) were acquired. Data represent the mean and SEM of n = 8 replicates. N.D., not determined.
