Native Baker's yeast (S. cerevisiae) D-Ribulose-5-phosphate 3-Epimerase


Cat No.
NATE-0659
Description
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.

Applications
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. This product is from baker’s yeast and is provided as a lyophilized powder. It is useful in enzyme systems requiring low sulfate.
Form
lyophilized powder. Lyophilized and essentially sulfate-free; contains approx. 35% Citrate buffer salts.
Enzyme Commission Number
EC 5.1.3.1
Activity
50-100 units/mg protein (modified Warburg-Christian)
CAS No.
9024-20-8
Unit Definition
One unit will convert 1 μmole of D-ribulose 5-phosphate to D-xylulose 5-phosphate per min at pH 7.7 at 25°C when coupled with transketolase, α-glycerophosphate dehydrogenase, and triosephosphate isomerase.
Storage
−20°C
