Glycine 36-43 solute carrier family 6 member 9 Homo sapiens 58-63 17383967-5 2007 In this report, we demonstrate that the LeuT(Aa) structure represents a good working model of the Na(+)/Cl(-)-dependent neurotransmitters and that differences in substrate selectivity can be attributed to a single difference of a glycine residue in transmembrane domain 6 of GLYT1 for a serine residue at the corresponding position of GLYT2.
