abstract：:Intracellular degradation of vertebrate ornithine decarboxylase (ODC) is accelerated by polyamines, the products of the pathway controlled by ODC. Antizyme, a reversible, tightly binding protein inhibitor of ODC activity, is believed to be involved in this process. Mouse and Trypanosoma brucei ODCs are structurally si...
