生物活性/药理作用

RPE is a lloenzyme 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.

应 用

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.

样品准备说明

Lyophilized and essentially sulfate-free; contains approx. 35%citrate buffer salts

有效单位定义

One unit will convert 1μmole of D-ribulose 5-phosphate to D-xylulose 5-phosphate per min at pH7.7 at 25°C when coupled with transketolase, α-glycerophosphate dehydrogenase, and triosephosphate isomerase.
