PW088232 View Pathway	metabolic Spermidine and Spermine Biosynthesis Bos taurus The Spermidine and Spermine Biosynthesis pathway highlights the creation of these cruicial polyamines. Spermidine and spermine are produced in many tissues, as they are involved in the regulation of genetic processes from DNA synthesis to cell migration, proliferation, differentiation and apoptosis. These positiviely charged amines interact with negatively charged phosphates in nucleic acids to exert their regulatory effects on cellular processes. Spermidine originates from the action of spermidine synthase, which converts the methionine derivative S-adenosylmethionine and the ornithine derivative putrescine into spermidine 5'-methylthioadenosine. Spermidine is subsequently processed into spermine by spermine synthase in the presence of the aminopropyl donor, S-adenosylmethioninamine.

PW002085 View Pathway	metabolic Spermidine Biosynthesis and Metabolism Escherichia coli Spermidine metabolism starts with S-adenosyl-L-methionine reacting with a hydrogen ion through a adenosylmethionine decarboxylase resulting in the release of a carbon dioxide and a S-adenosyl 3-(methylthio)propylamine. The later compound in turn reacts with putrescine resulting in the release of a hydrogen ion, a spermidine and a S-methyl-5'-thioadenosine. S-methyl-5'-thioadenosine in turn reacts with a water molecule through a 5-methylthioadenosine nucleosidase resulting in the release of a adenine and a S-methyl-5-thio-D-ribose which in in turn is released into the environment.

PW490800 View Pathway	metabolic Spermidine Biosynthesis I Bacteroides pyogenes DSM 20611 = JCM 6294 Spermidine is formed from decarboxy-SAM and putrescine by catalyzing spermidine synthase (also knowns as polyamine aminopropyltransferase). The source of putrescine is transported from outside of cell by putrescine/spermidine ABC transporter. Decarboxy-SAM comes from S-Adenosylmethionine with catalyzation of adenosylmethionine decarboxylase and cofactors: pyruvic acid and magnesium. The other product of the aminopropyltransferase reaction is S-methyl-5'-thioadenosine (MTA), which can be recycled back to L-methionine in many organisms, but not in E. coli. Inhibition of E. coli adenosylmethionine decarboxylase by spermidine appears to be the most significant regulator of polyamine biosynthesis, probably limiting it when the intracellular spermidine concentration becomes excessive. In E. coli most intracellular spermidine is bound to nucleic acids and phospholipids.
