[[http://www.uniprot.org/uniprot/SAT1_HUMAN SAT1_HUMAN]] Enzyme which catalyzes the acetylation of polyamines. Substrate specificity: norspermidine = spermidine >> spermine > N(1)-acetylspermine > putrescine. This highly regulated enzyme allows a fine attenuation of the intracellular concentration of polyamines. Also involved in the regulation of polyamine transport out of cells. Acts on 1,3-diaminopropane, 1,5-diaminopentane, putrescine, spermidine (forming N(1)- and N(8)-acetylspermidine), spermine, N(1)-acetylspermidine and N(8)-acetylspermidine. | [[http://www.uniprot.org/uniprot/SAT1_HUMAN SAT1_HUMAN]] Enzyme which catalyzes the acetylation of polyamines.
