Diamine transaminase

In enzymology, a diamine transaminase is an enzyme that catalyzes the chemical reaction


 * an alpha,omega-diamine + 2-oxoglutarate $$\rightleftharpoons$$ an omega-aminoaldehyde + L-glutamate

Thus, the two substrates of this enzyme are alpha,omega-diamine and 2-oxoglutarate, whereas its two products are omega-aminoaldehyde 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 diamine:2-oxoglutarate aminotransferase. Other names in common use include amine transaminase, amine-ketoacid transaminase, diamine aminotransferase, and diamine-ketoglutaric transaminase. This enzyme participates in urea cycle and metabolism of amino groups.
