Description Diaminobutyrate-2-oxoglutarate transaminase.
Alternative names L-2,4-diaminobutyrate:2-ketoglutarate 4-aminotransferase;
2,4-diaminobutyrate 4-aminotransferase;
Diaminobutyrate transaminase;
DABA aminotransferase.
Catalyzed reaction L-2,4-diaminobutyrate + 2-oxoglutarate = L-glutamate + L-aspartic 4-semialdehyde.
Cofactor Pyridoxal-phosphate; Potassium.
Comments -!- Involved in the formation of 1,3-diaminopropane in Haemophilus influenzae and Acinetobacter baumannii.
-!- A product of the ddc gene that also encodes L-2,4-diaminobutyrate decarboxylase in Acinetobacter baumannii.
-!- Differs from EC, diaminobutyrate-pyruvate transaminase which has pyruvate as the amino-group acceptor.

This is the first enzyme in the ectoine biosynthesis pathway, the other enzymes involved being EC and EC
