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

inquiry

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
