The action of uroporphyrin I (URO I) on the activity of red cell uroporphyrinogen decarboxylase (URO-D) in the dark and under UV light was studied. Light-dependent-and light-independent inactivation was observed. Both effects increased at increasing concentrations of URO I, the

Uroporphyrin and protoporphyrin produce alterations on 5-aminolevulinic acid dehydratase and porphobilinogen deaminase, as a result of a direct effect of porphyrins on the protein structure. With the aim of assessing the possible protection from the porphyrins effect on the proteins
Simon Y L Ching et al.
Analytical biochemistry, 353(2), 257-265 (2006-03-28)
Few methods for assessing total antioxidant capacity (TAC) include both the percentage of inhibition and the length of inhibition in the measurement. Available methods require above ambient constant temperature incubation, reaction preheating, and/or separate assays for testing hydrophilic and hydrophobic

Journal of enzyme inhibition, 10(2), 141-146 (1996-01-01)
The effect of uroporphyrin I (UI) on several cytosolic and mitochondrial enzymes (succinyl CoA synthetase, delta-aminolevulinic acid synthetase, rhodanese, lactate dehydrogenase) has been examined. All the enzymes were inactivated in the presence of the porphyrin both in the dark and
