Glycine 95-98 solute carrier family 15 member 1 Homo sapiens 35-41 17407174-8 2007 Translocation through the intestinal membrane, mediated by hPEPT1, was measured by recording the membrane potential relative to that induced by the known substrate Gly-Sar. Glycine 164-167 solute carrier family 15 member 1 Homo sapiens 59-65
