[[http://www.uniprot.org/uniprot/PAIA_BACSU PAIA_BACSU]] Possesses N1-acetyltransferase activity toward polyamine substrates including spermidine and spermine. Can acetylate both spermidine and spermine. In this way it may function in regulating intracellular polyamine concentrations and/or binding capabilities. In addition to preventing toxicity due to polyamine excess, this function may also serve to regulate expression of certain bacterial gene products such as those involved in sporulation.<ref>PMID:16210326</ref>
