In enzymology, a diaminobutyrate-2-oxoglutarate transaminase (EC 2.6.1.76) is an enzyme that catalyzes the chemical reaction

L-2,4-diaminobutanoate + 2-oxoglutarate L-aspartate 4-semialdehyde + L-glutamate

Thus, the two substrates of this enzyme are L-2,4-diaminobutanoate and 2-oxoglutarate, whereas its two products are L-aspartate 4-semialdehyde and L-glutamate.

This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is L-2,4-diaminobutanoate:2-oxoglutarate 4-aminotransferase. Other names in common use include L-2,4-diaminobutyrate:2-ketoglutarate 4-aminotransferase, 2,4-diaminobutyrate 4-aminotransferase, diaminobutyrate aminotransferase, DABA aminotransferase, DAB aminotransferase, EctB, diaminibutyric acid aminotransferase, and L-2,4-diaminobutyrate:2-oxoglutarate 4-aminotransferase. This enzyme participates in glycine, serine and threonine metabolism.

Aspartate transaminase (AST) or aspartate aminotransferase, also known as AspAT/ASAT/AAT or (serum) glutamic oxaloacetic transaminase, is a pyridoxal phosphate (PLP)-dependent transaminase enzyme that was first described by Arthur Karmen and colleagues in 1954. AST catalyzes the reversible transfer of an α-amino group between aspartate and glutamate and, as such, is an important enzyme in amino acid metabolism. AST is found in the liver, heart, skeletal muscle, kidneys, brain, red blood cells and gall bladder. Serum AST level, serum ALT level, and their ratio are commonly measured clinically as biomarkers for liver health. The tests are part of blood panels.

Amino acid synthesis is the set of biochemical processes by which the amino acids are produced. The substrates for these processes are various compounds in the organism's diet or growth media. Not all organisms are able to synthesize all amino acids. For example, humans can synthesize 11 of the 20 standard amino acids. These 11 are called the non-essential amino acids).
