CC   -!- FUNCTION: Catalyzes the acetylation of L-2,4-diaminobutyrate (DABA) to
CC       gamma-N-acetyl-alpha,gamma-diaminobutyric acid (ADABA) with acetyl
CC       coenzyme A. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=acetyl-CoA + L-2,4-diaminobutanoate = (2S)-4-acetamido-2-
CC         aminobutanoate + CoA + H(+); Xref=Rhea:RHEA:16901, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:57287, ChEBI:CHEBI:57288, ChEBI:CHEBI:58761,
CC         ChEBI:CHEBI:58929; EC=2.3.1.178;
CC   -!- PATHWAY: Amine and polyamine biosynthesis; ectoine biosynthesis; L-
CC       ectoine from L-aspartate 4-semialdehyde: step 2/3.
CC   -!- SIMILARITY: Belongs to the acetyltransferase family. EctA subfamily.
CC       {ECO:0000305}.
