Table 2. Vmax and Km values and inhibition patterns of PEPCK-C isoenzymes in the presence of glyceroneogenic substrates and compound 1.

[Compound 1] (μM) OAA GTP
Vmax (μmol min-1 mg-1) Km (μM) Vmax (μmol min-1 mg-1) Km (μM)
139Met 0 μM 21.3 ± 3.7 22 ± 14 20.0 ± 1.9 96 ± 15
139Met 50 μM 6.7 ± 1.4 13 ± 5 7.8 ± 0.5 118 ± 14
139Leu 0 μM 21.8 ± 1.8 ns 14 ± 4 ns 22.5 ± 4.2 ns 99 ± 14 ns
139Leu 50 μM 9.4 ± 1.3 ns 11 ± 3 ns 7.2 ± 0.4 ns 155 ± 30 ns

Values given are the mean of three independent experiments ± SD. Differences in Vmax and Km between 139Met and 139Leu were calculated using two-sample t-test; ns: not significant.
