Ribulose phosphate-3-epimerase (RPE) is the enzyme that catalyzes the conversion of 5-phosphate ribulose into xylulose-5-phosphate catalyzed . This reaction is a step in the pentose phosphate pathway in all living things and in the assimilation of carbon dioxide in plants.
Catalyzed reaction equilibrium
Ribulose-5-phosphate is rearranged to xylulose-5-phosphate and vice versa. Further substrates are D-erythrose-, D-erythrulose- and D-threose-4-phosphate.
