Function
Aminoalkylphosphonate N-acetyltransferase which is able to acetylate a range of aminoalkylphosphonic acids, including (S)-1-aminoethylphosphonate ((S)-1AEP) and 2-aminoethylphosphonate, using acetyl-CoA as acetyl donor. Its physiological role in S.typhimurium is unclear. However, by acetylating (S)-1AEP, PhnO would protect against the deleterious effects of (S)-1AEP, a structural analog of D-alanine that has antibacterial properties.
