Biological Activity

Description

The RPE Protein is responsible for catalyzing the reversible epimerization of D-ribulose 5-phosphate to D-xylulose 5-phosphate. RPE Protein, Human (His) is the recombinant human-derived RPE protein, expressed by E. coli , with C-6*His labeled tag.

Background

The RPE Protein, an enzyme, plays a crucial role in the metabolism of vitamin A. It converts retinol to retinaldehyde, which is essential for vision. In addition, RPE Protein inhibits tumor growth and may have potential therapeutic applications in treating certain conditions.
