Description

Xylitol:Nadp+ 4-Oxidoreductase (L-Xylulose-Forming) is a highly specific oxidoreductase enzyme that catalyzes the NADP+-dependent conversion of xylitol to L-xylulose. This enzyme is a critical biocatalyst in specialized biochemical pathways, particularly within the pentose and glucuronate interconversions. It is essential for research and development in industrial biotechnology, pharmaceutical synthesis, and diagnostic reagent manufacturing. Our supply ensures high specific activity and lot-to-lot consistency for reliable experimental and production-scale outcomes.

Application

• Biocatalyst in Fine Chemical Synthesis: Used for the stereoselective production of L-xylulose and related sugar derivatives.
• Enzymatic Assay Reagent: A key component in diagnostic kits and research assays for metabolic pathway analysis.
• Pharmaceutical Intermediate Production: Facilitates the synthesis of novel drug candidates and complex carbohydrate-based therapeutics.
• Biochemical Research: Employed in studies of pentose metabolism, enzyme kinetics, and genetic disorders related to sugar metabolism.
• Food & Beverage Industry R&D: Investigated for potential applications in the modification of sweeteners and food additives.
• Enzyme Engineering Studies: Serves as a model enzyme for protein engineering to improve stability, activity, or substrate specificity.

Quality Control

Our enzyme products are manufactured and tested under strict quality management systems. Each batch is characterized for specific activity, protein content, and purity to ensure optimal performance. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing key parameters such as activity units, purity profile, and stability data. We adhere to relevant industry guidelines to support applications in research and GMP-compliant environments.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below. This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent moisture absorption, which can lead to loss of activity. Avoid repeated freeze-thaw cycles.
