Confers high-level resistance to glyphosate when overexpressed (PubMed:22089966). Overexpression has no effect on intracellular arabinose concentrations (PubMed:22952739). Induced by arabinose. Deletion increases intracellular arabinose concentrations as compared to the wild type. Belongs to the major facilitator superfamily. YhhS family. Extended N-terminus.
