AccessionGenProp0641
Namespermidine biosynthesis from putrescine and S-adenosylmethionine
TypePATHWAY
DescriptionSpermine, spermidine and putrescine are a family of polyamines (positively charged organic polycations) that are important for cellular growth, most likely by stabilizing polynucleotides and membranes. Spermidine is derived from putrescine and the 4-aminobutyrate moiety of methionine (indirectly via S-adenosyl methionine). Spermine is synthesized by a second addition of 4-aminobutyrate to spermidine, and is more commonly found in eukaryotes.
