General Information: The polyamines (the most common of which are putrescine, spermidine and spermine) are a group of positively charged organic polycations that are involved in many biological processes, including binding to nucleic acids, stabilizing membranes, and stimulating several enzymes. In plants, polyamines have been involved in senescence and morphogenesis . Their specific molecular functions in vivo are however not yet fully understood. putrescine and spermidine are found in all life forms, and spermine is found mostly in eukaryotes. spermidine is formed by the addition of a propylamine moiety to putrescine, catalyzed by an aminopropyltransferase termed spermidine synthase. The propylamine group is transferred from S-adenosyl-L-methioninamine, which is produced by the action of the pyruvoyl-containing enzyme adenosylmethionine decarboxylase. The other product of the aminopropyltransferase reaction is 5'-methylthioadenosine (MTA), which is recycled back to L-methionine.
