A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 2.3.1.178

Accepted Name
Diaminobutyrate acetyltransferase.
Alternative Name(s)
2,4-diaminobutanoate acetyltransferase.
DAB acetyltransferase.
DABA acetyltransferase.
DABAcT.
Diaminobutyric acid acetyltransferase.
L-2,4-diaminobutanoate acetyltransferase.
L-2,4-diaminobutyrate acetyltransferase.
Reaction catalysed
Acetyl-CoA + L-2,4-diaminobutanoate <=> CoA + N(4)-acetyl-L-2,4-diaminobutanoate
Cofactor(s)
Na(+) or K(+).
Comment(s)
  • Ornithine, lysine, aspartate, and alpha-, beta- and gamma- aminobutanoate cannot act as substrates.
  • However, acetyl-CoA can be replaced by propanoyl-CoA, although the reaction proceeds more slowly.
  • Forms part of the ectoine biosynthesis pathway.
