1 [(14)C]Glycine uptake by TR-MUL5 cells was Na(+)- and Cl(-)-dependent, and a saturable process with Michaelis-Menten constants of 48.6 microM and 4.53 mM, and inhibited by glycine transporter 1 (GlyT1) and system A substrates. Glycine solute carrier family 6 member 9 Rattus norvegicus
2 [(14)C]Glycine uptake by TR-MUL5 cells was Na(+)- and Cl(-)-dependent, and a saturable process with Michaelis-Menten constants of 48.6 microM and 4.53 mM, and inhibited by glycine transporter 1 (GlyT1) and system A substrates. Glycine solute carrier family 6 member 9 Rattus norvegicus
3 These uptake studies suggest that GlyT1 and system A are involved in [(14)C]glycine uptake for the high- and low-affinity processes, respectively, in TR-MUL5 cells. Glycine solute carrier family 6 member 9 Rattus norvegicus
4 In conclusion, GlyT1 and CAT1 most likely mediate glycine and L-arginine uptake, respectively, by Muller cells and are expected to play an important role in supplying precursors for creatine biosynthesis in Muller cells. Glycine solute carrier family 6 member 9 Rattus norvegicus
