... transport is impaired with the EC50 of L-serine >1mM. On the other hand, L-aspartate, L-glutamate and Lcysteate are transported with remarkably high affinity, considering they are not transported by wild type ASCT1 at neutral pH (156.9 ± 33 µM, 420.8 ± 114 µM and 1.8 ± 0.2 µM respectively). This ill ...
