Uptake of L-arabinose across the cytoplasmic membrane with the concomitant transport of protons into the cell (symport system) (PubMed:7030324, PubMed:6282256, PubMed:2836407). D-fucose, a nonmetabolizable analog of L-arabinose, is also a good substrate (PubMed:6282256). H(+)(in) + L-arabinose(in) = H(+)(out) + L-arabinose(out) D-fucose(in) + H(+)(in) = D-fucose(out) + H(+)(out) Symport activity is inhibited in the presence of the uncoupling agents carbonyl cyanide m-chlorophenylhydrazone (CCCP) and tetrachlorosalicylanilide and 2,4-dinitrophenol (PubMed:6282256). Activity is partially inhibited by N-ethylmaleimide (PubMed:7030324). Induced by arabinose (PubMed:6282256, PubMed:6319708). Transcription is dependent on the transcription factor AraC, the cAMP receptor protein (CRP) and cAMP (PubMed:6319708). Belongs to the major facilitator superfamily. Sugar transporter (TC 2.A.1.1) family.
