Norspermidine is a polyamine of similar structure to the more common spermidine. While norspermidine has been found to occur naturally in some species of plants, [1] [2] bacteria, [3] and algae, [4] it is not known to exist in humans.
Norspermidine is being researched for use as a cancer medication. [5] [6]
The enzyme ornithine decarboxylase (ODC) catalyzes the decarboxylation of ornithine to form putrescine. This reaction is the committed step in polyamine synthesis. In humans, this protein has 461 amino acids and forms a homodimer.
Spermine is a polyamine involved in cellular metabolism that is found in all eukaryotic cells. The precursor for synthesis of spermine is the amino acid ornithine. It is an essential growth factor in some bacteria as well. It is found as a polycation at physiological pH. Spermine is associated with nucleic acids and is thought to stabilize helical structure, particularly in viruses.
Spermidine is a polyamine compound found in ribosomes and living tissues, and having various metabolic functions within organisms. It was originally isolated from semen.
Spermidine synthase is an enzyme that catalyzes the transfer of the propylamine group from S-adenosylmethioninamine to putrescine in the biosynthesis of spermidine. The systematic name is S-adenosyl 3-(methylthio)propylamine:putrescine 3-aminopropyltransferase and it belongs to the group of aminopropyl transferases. It does not need any cofactors. Most spermidine synthases exist in solution as dimers.
Lactalbumin, alpha-, also known as LALBA, is a protein that in humans is encoded by the LALBA gene.
Cathepsin A is an enzyme that is classified both as a cathepsin and a carboxypeptidase. In humans, it is encoded by the CTSA gene.
Mitochondrial uncoupling protein 2 is a protein that in humans is encoded by the UCP2 gene.
Azurocidin also known as cationic antimicrobial protein CAP37 or heparin-binding protein (HBP) is a protein that in humans is encoded by the AZU1 gene.
Diamine acetyltransferase 1 is an enzyme that in humans is encoded by the SAT1 gene found on the X chromosome.
Ornithine decarboxylase antizyme is an enzyme that in humans is encoded by the OAZ1 gene.
40S ribosomal protein S10 is a protein that in humans is encoded by the RPS10 gene.
RNA binding motif protein 9 (RBM9), also known as Rbfox2, is a protein which in humans is encoded by the RBM9 gene.
COP9 signalosome complex subunit 7b is a protein that in humans is encoded by the COPS7B gene.
Fasciculation and elongation protein zeta-2 is a protein that in humans is encoded by the FEZ2 gene.
Peroxisomal N(1)-acetyl-spermine/spermidine oxidase is an enzyme that in humans is encoded by the PAOX gene.
Ornithine decarboxylase antizyme 2 is an enzyme that in humans is encoded by the OAZ2 gene.
Diamine acetyltransferase 2 is an enzyme that in humans is encoded by the SAT2 gene. SAT2 maintains a key metabolic glutamine/glutamate balance underpinning retrograde signaling by dendritic release of the neurotransmitter glutamate.
A ureohydrolase is a type of hydrolase enzyme.
A polyamine is an organic compound having more than two amino groups. Alkyl polyamines occur naturally but are also synthetic. Alkylpolyamines are colorless, hygroscopic, and water soluble. Near neutral pH, they exist as the ammonium derivatives. Most aromatic polyamines are crystalline solids at room temperature.
Spermine oxidase (EC 1.5.3.16, PAOh1/SMO, AtPAO1, AtPAO4, SMO) is an enzyme with systematic name spermidine:oxygen oxidoreductase (spermidine-forming). This enzyme catalyses the following chemical reaction
