Шаблон:Infobox enzyme In enzymology, an adenosylmethionine-8-amino-7-oxononanoate transaminase (Шаблон:EC number) is an enzyme that catalyzes the chemical reaction

S-adenosyl-L-methionine + 8-amino-7-oxononanoate <math>\rightleftharpoons</math> S-adenosyl-4-methylthio-2-oxobutanoate + 7,8-diaminononanoate

Thus, the two substrates of this enzyme are S-adenosyl-L-methionine and 8-amino-7-oxononanoate, whereas its two products are S-adenosyl-4-methylthio-2-oxobutanoate and 7,8-diaminononanoate.

This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is S-adenosyl-L-methionine:8-amino-7-oxononanoate aminotransferase. Other names in common use include 7,8-diaminonanoate transaminase, 7,8-diaminononanoate transaminase, DAPA transaminase, 7,8-diaminopelargonic acid aminotransferase, DAPA aminotransferase, 7-keto-8-aminopelargonic acid, diaminopelargonate synthase, and 7-keto-8-aminopelargonic acid aminotransferase. This enzyme participates in biotin metabolism. It employs one cofactor, pyridoxal phosphate.
