4.1.1.86
Description Diaminobutyrate decarboxylase
Alternative names DABA decarboxylase;
L-2,4-diaminobutyrate decarboxylase.
Catalyzed reaction L-2,4-diaminobutyrate = 1,3-diaminopropane + CO(2).
Cofactor Pyridoxal-phosphate; divalent metal ion
Comments -!- N(4)-acetyl-L-2,4-diaminobutanoate, 2,3-diaminopropanoate, ornithine and lysine are not substrates.
-!-In Acinetobacter baumannii it is cotranscribed with the neighboring dat gene that encodes EC 2.6.1.76, which can supply the substrate for the decarboxylase.
PDB 2QMA;
Organisms -Eubacteria
