Uroporhyrinogen decarboxylase from mouse mammary carcinoma and liver of normal and tumor-bearing mouse
1. 1. URO-D was investigated in crude extracts from mouse mammary carcinoma, normal mouse (NM) liver and tumor-bearing mouse (TBM) liver. 2. 2. URO-D from TBM liver and tumor appears to be more sensitive to increasing concentrations of UROgen than the NM liver enzyme. 3. 3. In tumor the rate-limitin...

URO-D from TBM liver and tumor appears to be more sensitive to increasing concentrations of UROgen than the NM liver enzyme. 3. 3. In tumor the rate-limiting step seems to be the decarboxylation of the first carboxyl group, but this was not so clear for the NM and the TBM liver URO-D. 4. 4. URO-D activity was enhanced when incubated at higher temperatures in the presence of its substrate, suggesting that UROgen might afford some protection of the enzyme against heat inactivation. 5. 5.
