In enzymology, an arabinose-5-phosphate isomerase (EC 5.3.1.13) is an enzyme that catalyzes the chemical reaction

D-arabinose 5-phosphate [math]\displaystyle{ \rightleftharpoons }[/math] D-ribulose 5-phosphate

Hence, this enzyme has one substrate, D-arabinose 5-phosphate, and one product, D-ribulose 5-phosphate.

This enzyme belongs to the family of isomerases, specifically those intramolecular oxidoreductases interconverting aldoses and ketoses. The systematic name of this enzyme class is D-arabinose-5-phosphate aldose-ketose-isomerase. Other names in common use include arabinose phosphate isomerase, phosphoarabinoisomerase, and D-arabinose-5-phosphate ketol-isomerase.
