CC -!- FUNCTION: Catalyzes the sodium-dependent uptake of extracellular D-
CC alanine and L-alanine (PubMed:15659675, PubMed:30659158). Can also
CC transport glycine (PubMed:30659158). Binds glycine and both enantiomers
CC of alanine, while strictly excluding other amino acids
CC (PubMed:30659158). {ECO:0000269|PubMed:15659675,
CC ECO:0000269|PubMed:30659158}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-alanine(in) + Na(+)(in) = D-alanine(out) + Na(+)(out);

CC PhysiologicalDirection=right-to-left; Xref=Rhea:RHEA:68230;
CC Evidence={ECO:0000305|PubMed:30659158};
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:30659158};
CC Multi-pass membrane protein {ECO:0000269|PubMed:30659158}.
CC -!- DOMAIN: Maintains pseudo twofold symmetry even though it contains an
CC uneven number of transmembrane domains. {ECO:0000269|PubMed:30659158}.
CC -!- DISRUPTION PHENOTYPE: No growth on L- or D-alanine.
CC {ECO:0000269|PubMed:15659675}.
CC -!- SIMILARITY: Belongs to the alanine or glycine:cation symporter (AGCS)
CC (TC 2.A.25) family. {ECO:0000305}.
