Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0002589
UniProt IDP21673
Primary gene name(s)SAT1
Synonym gene name(s)SAT
Protein nameDiamine acetyltransferase 1
Protein functionEnzyme 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. {ECO:0000269|PubMed:16455797, ECO:0000269|PubMed:17516632}.
