Percentage of Gly-Sar uptake activities by transporters with alanine mutations of residues in loop 6–7 of hPEPT1 relative to WT-hPEPT1 (n = 4–7 experiments per mutation). [3H]Gly-Sar uptake (0.5 μCi/ml, 10 min at 37°C) was measured 72 h posttransfection in HEK293 cells. Background uptake of mock-transfected HEK293 cells was subtracted. *P < 0.05 vs. WT-hPEPT1 uptake
