ribulose-phosphate 3-epimerase

ri·bu·lose-phos·phate 3-e·pim·er·ase

(rī'byū-lōs-fos'fāt ep'i-mēr'ās),
An enzyme catalyzing the reversible interconversion of d-xylulose 5-phosphate and its epimer, d-ribulose 5-phosphate; a step in the nonoxidative phase of the pentose phosphate pathway.

Xylulose-5-phoshpate and ribulose-5-phosphate are interconversed by the ribulose-phosphate 3-epimerase (RPE) and involved in the pentose phosphate pathway (PPP).
