A distinct, Na+-dependent glycine transport system in avian small intestine

Glycine Transport by Human Diploid Fibroblasts—Absence of a Defect in Cells from Patients with Nonketotic Hyperglycinemia

“…In human fibroblasts, there appears to exist two distinct systems similar to the L system (15). Glycine has been shown to be transported by a variety of systems (18,19,20). Different mechanisms of glycine uptake exist in various mammalian tissues, e.g., two systems in ascites cells (21) and an irninoglycine system in renal tubules (1 1).…”
