CC -!- FUNCTION: Enzyme which catalyzes the acetylation of polyamines.
CC Substrate specificity: norspermidine = spermidine >> spermine > N(1)-
CC acetylspermine. This highly regulated enzyme allows a fine attenuation
CC of the intracellular concentration of polyamines. Also involved in the
CC regulation of polyamine transport out of cells. Also acts on 1,3-
CC diaminopropane and 1,5-diaminopentane. {ECO:0000250|UniProtKB:P21673}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=acetyl-CoA + an alkane-alpha,omega-diamine = an N-
CC acetylalkane-alpha,omega-diamine + CoA + H(+); Xref=Rhea:RHEA:11116,

CC Evidence={ECO:0000250|UniProtKB:P21673};
CC -!- PATHWAY: Amine and polyamine degradation; putrescine degradation; N-
CC acetylputrescine from putrescine: step 1/1.
CC {ECO:0000250|UniProtKB:P21673}.
CC -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:P21673}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol
CC {ECO:0000250|UniProtKB:P21673}.
CC -!- SIMILARITY: Belongs to the acetyltransferase family. {ECO:0000305}.
