EC 2.3.1.178 Details
EC number
2.3.1.178
Accepted name
diaminobutyrate acetyltransferase
Reaction
acetyl-CoA + L-2,4-diaminobutanoate = CoA + (2S)-4-acetamido-2-aminobutanoate
Other name(s)
L-2,4-diaminobutyrate acetyltransferase,
L-2,4-diaminobutanoate acetyltransferase,
EctA,
diaminobutyric acid acetyltransferase,
DABA acetyltransferase,
2,4-diaminobutanoate acetyltransferase,
DAB acetyltransferase,
DABAcT,
acetyl-CoA:L-2,4-diaminobutanoate 4-N-acetyltransferase
Systematic name
acetyl-CoA:L-2,4-diaminobutanoate N4-acetyltransferase
CAS registry number
130456-92-7
Comment
Requires Na+ or K+ for maximal activity [3]. Ornithine, lysine, aspartate, and α-, β- and γ-aminobutanoate cannot act as substrates [3]. However, acetyl-CoA can be replaced by propanoyl-CoA, although the reaction proceeds more slowly [3]. Forms part of the ectoine-biosynthesis pathway.
