Two cationic amino acid transport systems in human placental basal plasma membranes
Transport of cationic amino acids in basal (fetal facing) plasma membranes was investigated by characterization of L-( super(3)H)lysine and L-( super(3)H)arginine uptake in membrane vesicles isolated from term human placentas. At least two Na super(+)-independent systems were present. Lysine concent...

| Zusammenfassung: | Transport of cationic amino acids in basal (fetal facing) plasma membranes was investigated by characterization of L-( super(3)H)lysine and L-( super(3)H)arginine uptake in membrane vesicles isolated from term human placentas. At least two Na super(+)-independent systems were present. Lysine concentration dependence data were fit by a two-system model. |
