3.A.1.4.3
General L- (and D-)amino acid uptake porter (transports acidic, basic, polar, semipolar and hydrophobic amino acids). The amino and carboxyl groups do not need to be α since γ-aminobutyric acid (GABA) is a substrate. The system may function with additional binding proteins since L-alanine uptake is not dependent on BraC.

Species:Rhizobium leguminosarum (biovar viciae) [387]
Number of TMSs:1
Location1 / Topology2 / Orientation3: Membrane1 / Multi-pass membrane protein2
