Ribulose-5-phosphate 3-epimerase (RPE) is an enzyme that catalyzes the conversion of ribulose-5-phosphate to xylulose-5-phosphate. This reaction is a key step in the pentose phosphate pathway, which is crucial for the production of NADPH and pentose sugars, essential for various biosynthetic processes. RPE is found in the cytoplasm of eukaryotic cells and is encoded by the RPE gene. The enzyme plays a significant role in maintaining cellular redox balance and is involved in the regulation of glucose metabolism. Mutations in the RPE gene have been associated with specific genetic disorders, including ribulose-5-phosphate 3-epimerase deficiency, which can lead to hemolytic anemia and other metabolic abnormalities. The enzyme's activity is regulated by various factors, including allosteric effectors and post-translational modifications. Understanding the function and regulation of RPE is important for comprehending its role in cellular metabolism and its potential implications in disease.
