Structural and degradative aspects of ornithine decarboxylase antizyme inhibitor 2

FEBS Open Bio, 2014
Ornithine decarboxylase (ODC) is the key enzyme in the polyamine biosynthetic pathway. ODC levels are controlled by polyamines through the induction of antizymes (AZs), small proteins that inhibit ODC and target it to proteasomal degradation without ...

Post-transcriptional regulation of ornithine decarboxylase in Xenopus laevis oocytes.

, 1990
International audienceThe level at which ornithine decarboxylase expression is regulated in growing oocytes has been investigated. Immunoprecipitation of the in vivo labelled proteins showed that ornithine decarboxylase accumulated less rapidly in stage ...

Regulation of ornithine decarboxylase from Mycobacterium smegmatis

, 1988
The activity of ornithine decarboxylase in Mycobacterium smegmatis is regulated by a novel macromolecular inhibitor-a ribonucleic acid. Addition of polyamines to the growth medium enhances the level of this inhibitor, suggesting that the level of this ...

Retinoic Acid Modulation of Ultraviolet Light-induced Epidermal Ornithine Decarboxylase Activity [PDF]

, 1982
Irradiation of skin with ultraviolet light of sunburn range (UVB) leads to a large and rapid induction of the polyamine biosynthetic enzyme ornithine decarboxylase in the epidermis.

Investigation on Ornithine Decarboxylase Activity and Level of Putrescine, Spermidine and Spermine in Hydatid Cyst

Journal of Ardabil University of Medical Sciences, 2017
Background & objectives: Polyamines such as putrescine, spermidine, and spermine are ubiquitous in all eukaryotic cells and play an essential role in cell division and differentiation. One way of polyamine biosynthesis is done by ornithine decarboxylase (

Characterization of OAZ1 and its potential functions in goose follicular development

Electronic Journal of Biotechnology, 2017
Background: Ornithine decarboxylase antizyme 1 (OAZ1) is an important regulator of polyamine synthesis and uptake. Our previous studies indicated that high OAZ1 expression in the ovaries of laying geese is responsible for poor egg production.

Permanent decrease in activity of ornithine decarboxylase antizyme in rat liver during chemical hepatocarcinogenesis

, 1983
This study was undertaken to determine whether or not there is failure of cellular control of L-ornithine decarboxylase activity by its antizyme, the only known natural intracellular inhibitor protein for L-ornithine decarboxylase activity, in rat liver ...

Optimized LC-MS method for simultaneous polyamine profiling and ADC/ODC activity quantification and evidence that ADCs are indispensable for flower development in tomato

Frontiers in Plant Science
IntroductionPolyamines (PAs) are essential for plant development and stress responses, requiring tight homeostatic regulation. As many PA enzymes are regulated post-transcriptionally, transcript-based methods cannot accurately predict protein abundance ...

Ornithine decarboxylase protein was present in the urogenital epithelium in the developing urogenital sinus.

, 2015
In the male UGS before budding at E15 (A) and E16 (B), ornithine decarboxylase protein (green) was present in the epithelium. As the buds emerged from the epithelium at E17 (E) and E18 (G), ornithine decarboxylase protein was still expressed in the ...
