L-arabinose enters E. coli unphosphorylated via a low-affinity proton-driven transporter (AraE) or a high-affinity ATP-driven system (AraFGH). Following entry, it is converted to L-ribulose-5-phosphate by an isomerase and kinase. L-ribulose-5-phosphate is then converted by an epimerase to the pentose phosphate pathway intermediate, D-xylulose-5-phosphate. D-xylulose-5-phosphate then enters metabolism pathways to become precursor metabolites, reducing power and metabolic energy.
