[[https://www.uniprot.org/uniprot/LYSN_THET2 LYSN_THET2]] Catalyzes the transfer of an amino group between 2-oxoadipate (2-OA) and glutamate (Glu) to yield alpha-aminodipate (AAA). It can also transaminate glutamate, leucine, and aromatic amino acids. It also contributes in the biosynthesis of other amino acids such as leucine.<ref>PMID:15256574</ref>

== Publication Abstract from PubMed ==

The extremely thermophilic bacterium Thermus thermophilus HB27 synthesizes lysine through alpha-aminoadipate (AAA). In this study, a T. thermophilus gene encoding the enzyme that catalyses transamination of AAA was cloned as a mammalian kynurenine/AAA aminotransferase (Kat2) gene homologue. A T. thermophilus mutant with disruption of the Kat2 homologue required a longer lag phase for growth and showed slower growth in minimal medium. Furthermore, addition of AAA or lysine shortened the lag phase and improved the growth rate. The Kat2 homologue was therefore termed lysN. LysN recognizes not only 2-oxoadipate, an intermediate of lysine biosynthesis, but also 2-oxoisocaproate, 2-oxoisovalerate and 2-oxo-3-methylvalerate, intermediates of leucine, valine and isoleucine biosyntheses, respectively, along with oxaloacetate, a compound in the TCA cycle, as an amino acceptor. These results suggest multiple roles of LysN in several cellular metabolic pathways including lysine and branched-chain amino acid biosyntheses.
