γ-DNP-L-2,4-DAB, also known as γ-Dinitrophenyl-L-2,4-Diaminobutyric acid, is a chemical compound that serves as a substrate for the enzyme diaminobutyric acid transaminase. This enzyme plays a crucial role in the metabolism of amino acids, particularly in the conversion of diaminobutyric acid to succinic semialdehyde. The γ-DNP-L-2,4-DAB compound is often used in biochemical research to study the activity and properties of this enzyme, as well as in the development of assays to measure its activity. It is a yellow crystalline solid that is sensitive to light and should be stored in a cool, dark place to maintain its stability.
