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       {ECO:0000250|UniProtKB:P21673}.
