Uptake of L-arabinose across the cytoplasmic membrane with the concomitant transport of protons into the cell (symport system) (PubMed:7665532). D-fucose, a nonmetabolizable analog of L-arabinose, is also a good substrate (PubMed:7665532). H(+)(in) + L-arabinose(in) = H(+)(out) + L-arabinose(out) D-fucose(in) + H(+)(in) = D-fucose(out) + H(+)(out) Belongs to the major facilitator superfamily. Sugar transporter (TC 2.A.1.1) family.
