Abstract excerpt
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-difluoromethylornithine, an irreversible inhibitor of the enzyme, and produced the enzyme protein to the extent of approx. 3-6% of total cytosolic protein. The rate of ODC synthesis in this cell line accounted for 25-50% of the rate of total protein...
