In enzymology, a 2-aminoadipate transaminase (EC 2.6.1.39) is an enzyme that catalyzes the chemical reaction

L-2-aminoadipate + 2-oxoglutarate 2-oxoadipate + L-glutamate

Thus, the two substrates of this enzyme are L-2-aminoadipate and 2-oxoglutarate, whereas its two products are 2-oxoadipate 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-aminoadipate:2-oxoglutarate aminotransferase. Other names in common use include alpha-aminoadipate aminotransferase, 2-aminoadipate aminotransferase, 2-aminoadipic aminotransferase, glutamic-ketoadipic transaminase, and glutamate-alpha-ketoadipate transaminase. This enzyme participates in lysine biosynthesis and lysine degradation. It employs one cofactor, pyridoxal phosphate.

Structural studies

As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 2DTV.

α-Aminoadipate pathway Chemical compound

The α-aminoadipate pathway is a biochemical pathway for the synthesis of the amino acid L-lysine. In the eukaryotes, this pathway is unique to several species of yeast, higher fungi, and the euglenids. It has also been reported from bacteria of the genus Thermus and also in Pyrococcus horikoshii, potentially suggesting a wider distribution than previously thought. This uniqueness of the pathway makes it a potentially interesting target for antimycotics.

Kynurenine/alpha-aminoadipate aminotransferase, mitochondrial, also known as alpha-aminoadipate aminotransferase and kynurenine aminotransferase 2, is a mitochondrial enzyme that in humans is encoded by the AADAT gene. It converts alpha-aminoadipate to alpha-ketoadipate. It is also one of the Kynurenine—oxoglutarate transaminases.
