Ornithine Decarboxylase in Skin
Journal of Investigative Dermatology, 1980 Ornithine decarboxylase (ODC) was discovered in animal tissues in 1968 [1,2] and interest in its activity and regulation has led to a rapidly and still expanding literature on the enzyme. Several comprehensive reviews have already appeared [3–6]. This article emphasizes our current knowledge of ODC in mammalian skin.

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

Determinants of the differential antizyme-binding affinity of ornithine decarboxylase. [PDF]
PLoS ONE, 2011 Ornithine decarboxylase (ODC) is a ubiquitous enzyme that is conserved in all species from bacteria to humans. Mammalian ODC is degraded by the proteasome in a ubiquitin-independent manner by direct binding to the antizyme (AZ).

Suppression of 12-O-tetradecanoylphorbol-13-acetate-induced ornithine decarboxylase activity by resveratrol derivatives [PDF]
, 2012 As demonstrated previously, resveratrol (3,4',5-trihydroxy-trans-stilbene) inhibits 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced ornithine decarboxylase (ODC), the key rate limiting enzyme in mammalian polyamine synthesis.

Regulation of Ornithine Decarboxylase [PDF]
Journal of Biological Chemistry, 2006 Ornithine decarboxylase (ODC) initiates the polyamine biosynthetic pathway. The amount of ODC is altered in response to many growth factors, oncogenes, and tumor promoters and to changes in polyamine levels. Susceptibility to tumor development is increased in transgenic mice expressing high levels of ODC and is decreased in mice with reduced ODC due to

Putrescine Biosynthesis Inhibition in Tomato by DFMA and DFMO Treatment
Bio-Protocol, 2016 This protocol can be used to inhibit the biosynthesis of polyamines, specifically putrescine, in tomato plants grown with NH4+ as a solely N source. In general, polyamines are positively charged small metabolites implicated in physiological processes ...

Hydroxylamine Analogue of Agmatine: Magic Bullet for Arginine Decarboxylase
Biomolecules, 2020 The biogenic polyamines, spermine, spermidine (Spd) and putrescine (Put) are present at micro-millimolar concentrations in eukaryotic and prokaryotic cells (many prokaryotes have no spermine), participating in the regulation of cellular proliferation and
