This compound then donates its n-propylamine group in the biosynthesis of polyamines such as spermidine and spermine from putrescine.
12.
A mixture of 5-methoxysalicylic acid and spermine can be used as a matrix for oligonucleotides analysis in MALDI mass spectrometry.
13.
Allosteric receptor binding sites for zinc, proteins and the polyamines spermidine and spermine are also modulators for the NMDA receptor channels.
14.
Polyamines ( spermidine and spermine ) have been observed to be released from " S . boulardii " in the rat ileum.
15.
QRICH2 protein has some sequence similarities with the spermidine / spermine N ( 1 )-acetyl-like protein 1 in several species.
16.
The ornithine decarboxylation reaction catalyzed by ornithine decarboxylase is the first and committed step in the synthesis of polyamines, particularly putrescine, spermidine and spermine.
17.
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.
18.
Spermidine / spermine N ( 1 )-acetyltransferase ( SPD / SPM acetyltransferase ) is a rate-limiting enzyme in the catabolic pathway of polyamine metabolism.
19.
It's the type of chemical ( Spermine and Spermidine in particular ) that give semen its smell .-- BluePlatypus 01 : 49, 23 April 2006 ( UTC)
20.
It catalyzes the N ( 1 )-acetylation of spermidine and spermine and, by the successive activity of polyamine oxidase, spermine can be converted to spermidine and spermidine to putrescine.
