Alanine dehydrogenase (EC 1.4.1.1) is an enzyme that plays a crucial role in amino acid metabolism, specifically in the reversible conversion of L-alanine to pyruvate and ammonia. This reaction is coupled with the reduction of NAD+ to NADH, which makes alanine dehydrogenase important for cellular redox balance and energy metabolism.
Alfa Chemistry offers high-quality alanine dehydrogenase that is briefly purified from engineered E. coli.

Biological Role
- Amino Acid Metabolism: Alanine dehydrogenase is pivotal in the catabolism and synthesis of alanine. It helps maintain the balance of amino acids in the cell.
- Nitrogen Metabolism: By producing ammonia (NH3), the enzyme contributes to nitrogen metabolism, which is essential for the synthesis of nucleotides and other nitrogenous compounds.
- Energy Production: The conversion of L-alanine to pyruvate feeds into the Krebs cycle, thus aiding in cellular respiration and energy production.
- Redox Balance: The production of NADH in the reaction can be used in the electron transport chain to produce ATP, thus playing a role in the cell's energy economy.
Applications
- Industrial and Biotechnological: Alanine dehydrogenase is used in the biosynthesis of L-alanine, which is an important amino acid for various applications including pharmaceuticals, food additives, and supplements.
- Research: It is used as a model enzyme to study amino acid metabolism and enzyme kinetics.
- Clinical: Understanding the function and regulation of alanine dehydrogenase can provide insights into metabolic disorders related to amino acid imbalances.
