A track record of studies on the regulatory mechanism of ornithine decarboxylase. From circadian rhythms to regulated degradation

A track record of studies on the regulatory mechanism of ornithine decarboxylase. From circadian rhythms to regulated degradation
This paper summarizes results of a quarter-century study on the regulatory mechanism of ornithine decarboxylase (ODC), a key enzyme in polyamine synthesis. ODC turns over rapidly and is under negative feedback regulation by polyamines, which accelerate ODC degradation and induce an ODC-inhibitory protein, antizyme. Rat-liver ODC levels exhibit a circadian rhythm with the peak at night, owing to the feeding pattern.
