Protease synthase and sporulation negative regulatory protein PAI 1
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Involved in the protection against polyamine toxicity by regulating their concentration. Also could 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.
