Publisher Summary Ornithine decarboxylase (ODC) catalyzes the formation of putrescine
from ornithine, the initial step in the synthesis of the polyamines spermidine and spermine …

Ornithine decarboxylase, the initial enzyme in the polyamine biosynthetic pathway, is
induced in target tissues in response to a variety of trophic agents including polypeptide and …

The activity of ornithine decarboxylase (ODC), the first and rate‐limiting enzyme in the
polyamine biosynthetic pathway, is dramatically increased in proliferating cells. In addition to …

Publisher Summary This chapter highlights the regulation and function of ornithine
decarboxylase (ODC) and of the polyamines. ODC catalyzes the synthesis of putrescine. It is …

Ornithine decarboxylase (ODC, L-ornithine carboxylyase, EC 4.1. 1.17) is the rate limiting
enzyme in the biosynthesis of polyamines. Its occurrence in animal tissue was reported …

The enzyme ornithine decarboxylase (ODC; EC 4.1. 1.17) catalyses the first and rate-limiting
step in polyamine biosynthesis. Its activity is markedly increased in rapidly growing or …

We have isolated from mouse FM3A cells a variant cell line, termed EXOD-1, that
overproduces ornithine decarboxylase (ODC). The cells were resistant to alpha …

Ornithine decarboxylase, the first enzyme in the polyamine biosynthetic pathway, is induced
by androgens in the mouse kidney. Enzyme activity, as well as enzyme protein levels are …

Ornithine decarboxylase (ODC, EC 4.1. 1.17) expression is subject to negative feedback
regulation by the polyamines. The results of previous studies favor either translational or …
