Requires Na+ or K+ for maximal activity [3]. Ornithine, lysine, aspartate, and ¦Á-, ¦Â- and ¦Ã-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.
Cofactor
Na+ or K+
History
Reactions
Acetyl-CoA + L-2,4-diaminobutanoate = CoA + N(4)-acetyl-L-2,4- diaminobutanoate.
