Description

L-Transaminase, Branched-Chain is a specialized enzyme that catalyzes the reversible transfer of an amino group between branched-chain amino acids (leucine, isoleucine, valine) and α-ketoglutarate. This biocatalyst is critical for the biosynthesis and metabolic regulation of essential amino acids, offering high stereoselectivity and efficiency under mild reaction conditions. It is a vital tool for pharmaceutical manufacturers, research institutions, and fine chemical producers engaged in the synthesis of chiral amines, active pharmaceutical ingredients (APIs), and metabolic pathway studies.

Application

• Pharmaceutical Synthesis: Key biocatalyst for the asymmetric synthesis of chiral amine intermediates used in active pharmaceutical ingredients (APIs).
• Diagnostic Reagents: Used in clinical diagnostic kits for the quantitative determination of branched-chain amino acids in serum or plasma.
• Biochemical Research: Essential tool for in vitro studies of amino acid metabolism, enzyme kinetics, and metabolic pathway engineering.
• Fine Chemical Production: Enables green, sustainable manufacturing of high-value, optically pure amino acids and derivatives for agrochemicals and nutraceuticals.
• Food & Beverage Analysis: Employed in enzymatic assay methods to analyze amino acid content and profile in foodstuffs and nutritional supplements.
