Diaminobutyrate-pyruvate transaminase () is a pyridoxal phosphate-dependent enzyme that catalyzes the reversible chemical reaction
The two substrates of this enzyme characterised from the genus Xanthomonas are L-2,4-diaminobutanoic acid and pyruvic acid. Its products are (2S)-2-amino-4-oxobutanoic acid and L-alanine.
This enzyme is a transferase, specifically a transaminase, which transfer nitrogenous groups. The systematic name of this enzyme class is L-2,4-diaminobutanoate:pyruvate aminotransferase. Other names in common use include diaminobutyrate-pyruvate aminotransferase, and L-diaminobutyric acid transaminase.
