ID 4.1.1.86 DE diaminobutyrate decarboxylase. AN DABA DC. AN L-2,4-diaminobutanoate carboxy-lyase. AN L-2,4-diaminobutyrate decarboxylase. CA L-2,4-diaminobutanoate + H(+) = propane-1,3-diamine + CO2. CC -!- N(4)-acetyl-L-2,4-diaminobutanoate, 2,3-diaminopropanoate, ornithine CC and lysine are not substrates. CC -!- In Acinetobacter baumannii it is cotranscribed with the neighboring CC dat gene that encodes EC 2.6.1.76, which can supply the substrate for CC the decarboxylase.
