Characterization of a cyclic compound formed after spermine oxidation by lentil amine oxidase
, 1997 Spermine is a substrate of lentil seedling amine oxidase and is oxidized at terminal amino groups to a dialdehyde: 2 mol of hydrogen peroxide and two mol of ammonia per mol of spermine are formed.

THE EFFECT OF SPERMINE ON TUBERCLE BACILLI [PDF]
Journal of Experimental Medicine, 1952 A crystalline substance capable of suppressing the growth of a variety of mycobacteria in vitro has been isolated from extracts of tissue in acidified dilute ethanol. This inhibitory material was found to be equally active against virulent, attenuated, and avirulent variants of human and bovine tubercle bacilli, but had little or no effect on ...

Absence of spermine in filamentous fungi [PDF]
Journal of Bacteriology, 1977 Polyamines were examined in several yeasts and filamentous fungi. Whereas putrescine, spermidine, and spermine were present in the yeasts, spermine was not detected in any of the filamentous fungi.

Medicine Bulletin, EarlyView.ABSTRACT Background Colorectal cancer liver metastasis (CRLM) is the leading cause of mortality in colorectal cancer (CRC) patients, for which effective treatments remain limited. The mechanisms by which tumor cells evade immune surveillance and escape cytotoxic killing remain poorly understood.

Extracellular Spermine Activates DNA Methyltransferase 3A and 3B
, 2019 We first demonstrated that long-term increased polyamine (spermine, spermidine, putrescine) intake elevated blood spermine levels in mice and humans, and lifelong consumption of polyamine-rich chow inhibited aging-associated increase in aberrant DNA ...

Proteo‐transcriptomic insights into the venom composition of the ectoparasitoid Eupelmus urozonus
Pest Management Science, EarlyView.Integrated venom‐gland transcriptomics and venom proteomics of Eupelmus urozonus identified 316 venom proteins, including 75 secreted candidates, revealing diverse hydrolases, proteases/inhibitors and many uncharacterized effectors. Abstract BACKGROUND Ectoparasitoid venoms are ‘cocktails’ of bioactive molecules injected during oviposition to paralyze ...

The interaction of spermine and pentamines with DNA [PDF]
Biochemical Journal, 1987 We studied the effects of spermine, two naturally-occurring pentamines isolated from the thermophile Thermus thermophilus and one synthetic pentamine on the aggregation and ‘melting’ temperature of calf-thymus DNA and on the B-to-Z transition of poly(dG-me5dC). All pentamines caused aggregation of DNA at much lower concentrations than that of spermine.
