Putrescine, Spermidine, and Spermine
Putrescine was first isolated from putrifying meat and was thought of as a decomposition product; spermine was named from its occurrence in semen. These polyamines, however, are now known to have important roles in cell growth and differentiation. Their physiological significance can be studied by analyzing the consequences of depletion of the cellular polyamine content. The results include arr...

متن کاملSpermidine/spermine N-acetyltransferase Catalyzes Amantadine Acetylation
Amantadine acetylation was demonstrated to occur both in vivo and in vitro using transgenic male mice overexpressing spermidine/spermine N-acetyltransferase (SSAT). We previously reported that neither NAT1 nor NAT2 was responsible for catalyzing acetylation of the primary amine group of amantadine. We hypothesized that the inducible polyamine-catabolizing enzyme, SSAT, was an alternate pathway ...
متن کاملSpermine and spermidine reversed age-related cardiac deterioration in rats
Aging is the most important risk factor for cardiovascular disease (CVD). Slowing or reversing the physiological impact of heart aging may reduce morbidity and mortality associated with age-related CVD. The polyamines, spermine (SP) and spermidine (SPD) are essential for cell growth, differentiation and apoptosis, and levels of both decline with age. To explore the effects of these polyamines o...
متن کاملCompartmentalization of spermine and spermidine in the herpes simplex virion.
Enveloped particles of herpes simplex virus produced in human cells in culture contained spermidine and spermine, in a molar ratio of 1.6 +/- 0.2. The spermine present within the nucleocapsid is sufficient to neutralize at least 40% of the viral DNA. Disruption of the envelope with nonionic detergent and urea resulted in the selective loss of spermidine. Exogenous ornithine can function as a pr...
