Spermidine/spermine N(1)-acetyltransferase

UniProtKB accession:  P21340

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Involved in the protection against polyamine toxicity by regulating their concentration. Could also be involved in the negative control of sporulation as well as production of degradative enzymes such as alpha-amylase, levansucrase and alkaline phosphatase. Catalyzes the transfer of an acetyl group from acetyl coenzyme A (AcCoA) to an acceptor substrate and releases both CoA and the acetylated product. It possesses N1-acetyltransferase activity toward polyamine substrates including spermidine, spermine, aminopropylcadaverine, norspermidine, homospermidine, N(8)-acetylspermidine, diaminopropane and agmatine.
