The Spermine Synthase OsSPMS1 Regulates Seed Germination, Grain Size, and Yield1[OPEN] [PDF]

open access: yesPlant Physiology, 2018
OsSPMS1, a spermine synthase that participates in polyamine and ethylene homeostasis, plays an important role in seed germination, plant architecture, and yield in rice.

In silico and in vitro investigations of the mutability of disease-causing missense mutation sites in spermine synthase. [PDF]

open access: yesPLoS ONE, 2011
Spermine synthase (SMS) is a key enzyme controlling the concentration of spermidine and spermine in the cell. The importance of SMS is manifested by the fact that single missense mutations were found to cause Snyder-Robinson Syndrome (SRS).

Spermine synthase. [PDF]

open access: yesCell Mol Life Sci, 2010
Spermine is present in many organisms including animals, plants, some fungi, some archaea, and some bacteria. It is synthesized by spermine synthase, a highly specific aminopropyltransferase. This review describes spermine synthase structure, genetics, and function.

Multi-Temperature Crystallography of Polyamine Biosynthesis Enzymes Reveals Differing Active Site Conformations at RT than 100K [PDF]

open access: yesStructural Dynamics
The polyamine biosynthetic pathway synthesizes the polyamines putrescine, spermidine, and spermine from ornithine and S-adenosyl methionine. These polyamines are important molecules in metabolism and are associated with growth and proliferation of cells ...

Placental sex-dependent spermine synthesis regulates trophoblast gene expression through acetyl-coA metabolism and histone acetylation

open access: yesCommunications Biology, 2022
Sex-dependent metabolism of spermine alter trophoblast gene expression through acetyl-coA biosynthesis and histone acetylation, indicating that escape of spermine synthase from X-linked inactivation partially contributes to placental sex differences.

Specificity of mammalian spermidine synthase and spermine synthase [PDF]

open access: yesBiochemical Journal, 1981
1. The specificity of rat prostatic spermidine synthase and spermine synthase with respect to the amine acceptor of the propylamine group was studied. 2. Spermidine synthase could use cadaverine (1,5-diaminopentane) instead of putrescine, but the Km for cadaverine was much greater and the rate with 1mM-cadaverine was only 10% of that with putrescine. 1,

Studies of inhibition of rat spermidine synthase and spermine synthase [PDF]

open access: yesBiochemical Journal, 1980
1. S-Adenosyl-l-methionine, S-adenosyl-l-homocysteine, 5′-methylthioadenosine and a number of analogues having changes in the base, sugar or amino acid portions of the molecule were tested as potential inhibitors of spermidine synthase and spermine synthase from rat ventral prostate. 2. S-Adenosyl-l-methionine was inhibitory to these reactions, as were
