Spermine deficiency in Gy mice caused by deletion of the spermine synthase gene [PDF]

open access: yesHuman Molecular Genetics, 1998
Two mouse mutations gyro (Gy) and hypophosphatemia (Hyp) are mouse models for X-linked hypophosphatemic rickets and have been shown to be deleted for the 5' and 3' end of the mouse homolog of PHEX (phosphate regulating gene with homologies to endopeptidases on the X chromosome; formerly called PEX), respectively.

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

Difluoromethylornithine rebalances aberrant polyamine ratios in Snyder–Robinson syndrome

open access: yesEMBO Molecular Medicine, 2023
Snyder–Robinson syndrome (SRS) results from mutations in spermine synthase (SMS), which converts the polyamine spermidine into spermine. Affecting primarily males, common manifestations of SRS include intellectual disability, osteoporosis, hypotonia, and

Aminopropyltransferases involved in polyamine biosynthesis localize preferentially in the nucleus of plant cells. [PDF]

open access: yesPLoS ONE, 2012
Plant aminopropyltransferases consist of a group of enzymes that transfer aminopropyl groups derived from decarboxylated S-adenosyl-methionine (dcAdoMet or dcSAM) to propylamine acceptors to produce polyamines, ubiquitous metabolites with positive charge

Fluorinated analogues of spermidine as substrates of spermine synthase [PDF]

open access: yesEuropean Journal of Biochemistry, 1988
A series of mono‐and geminal difluorinated analogues of spermidine (4‐azaoctane‐1, 8‐diamine) have been tested as potential substrates of partially purified rat hepatoma (HTC) cell or pure bovine spleen spermine synthase (EC 2.5.1.22).Substitution of the hydrogen atoms of the methylene group at position 7 by one or two fluorine atoms decreases 8‐fold ...

In Silico Investigation of Mutability of Spermine Synthase [PDF]

open access: yesBiophysical Journal, 2011
Spermine Synthase (SMS) is an enzyme which controls spermidine/spermine concentrations, both of which are polyamines playing an important role for cell development. Recently we have investigated the effect of missense mutations (G56S, V132G and I150T) known to cause Synder-Robinson Syndrome (SRS) on SMS stability and dynamics.

Characterization of transgenic mice with widespread overexpression of spermine synthase [PDF]

open access: yesBiochemical Journal, 2004
A widespread increase in SpmS (spermine synthase) activity has been produced in transgenic mice using a construct in which the human SpmS cDNA was placed under the control of a composite CMV-IE (cytomegalovirus immediate early gene) enhancer–chicken β-actin promoter. Four separate founder CAG/SpmS mice were studied.

Spermine-Conjugated Short Proline-Rich Lipopeptides as Broad-Spectrum Intracellular Targeting Antibacterial Agents

open access: yes, 2022
Toward the design of new proline-rich peptidomimetics, a short peptide segment, present in several proline-rich antimicrobial peptides (AMPs), was selected.

Overexpression of SAMDC1 gene in Arabidopsis thaliana increases expression of defense-related genes as well as resistance to Pseudomonas syringae and Hyaloperonospora arabidopsidis

open access: yesFrontiers in Plant Science, 2014
It has been previously described that elevation of endogenous spermine levels in Arabidopsis could be achieved by transgenic overexpression of S-Adenosylmethionine decarboxylase (SAMDC) or Spermine synthase (SPMS).
