Application

D-Ribulose-5-phosphate 3-Epimerase is an enzyme that converts the reversible conversion of D-ribulose 5-phosphate into D-xylulose 5-phosphate, which is important for the cellular response against oxidative stress . D-Ribulose-5-phosphate 3-Epimerase is involved in the pentose phosphate pathway, pentose and glucuronate interconversions and carbon fixation. Product R3251 is from baker’s yeast and is provided as a lyophilized powder. It is useful in enzyme systems requiring low sulfate.

Biochem/physiol Actions

RPE is a metalloenzyme and has been shown to use the divalent Zn²⁺ ion predominantly for catalysis. Human D-ribulose-5-phosphate 3-epimerase (hRPE) has been shown to use Fe²⁺ for catalysis .
