Putrescine2
- They are structurally and biosynthetically related to the diamines putrescine and cadaverine. (wikipedia.org)
- Spermine and spermidine are natural polyamines that are produced mainly via decarboxylation of l-ornithine and the sequential transfer of aminopropyl groups from S-adenosylmethionine to putrescine by spermidine synthase and spermine synthase. (nih.gov)
Spermidine2
- The principal examples are the triamine spermidine and the tetraamine spermine. (wikipedia.org)
- Spermine and spermidine interact with intracellular and extracellular acidic residues of different nature, including nucleic acids, phospholipids, acidic proteins, carboxyl- and sulfate-containing polysaccharides. (nih.gov)
