SUMMARY A patient with hepatoerythropoietic porphyria (HEP) is described. He was shown by a family study to be homozygous for a gene that causes greater than 95% suppression of erythrocyte uroporphyrinogen decarboxylase activity.

1. 1. The action of uroporphyrin I on erythrocytic ALA-D activity under dark and light conditions was examined. 2. 2. Photo and non-photoinactivation of ALA-D induced by uroporphyrin I were observed. 3. 3. Both effects were dependent on uroporphyrin

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

The action of porphyrins, uroporphyrin I and III (URO I and URO III), pentacarboxylic porphyrin I (PENTA I), coproporphyrin I and III (COPRO I and COPRO III), protoporphyrin IX (PROTO IX) and mesoporphyrin (MESO), on the activity of human erythrocyte

1. 1. The effect of URO I on the activity of ALA-D, PBGase, deaminase and URO-D, both in aerobiosis and anaerobiosis, was studied. 2. 2. Photoinactivation of the enzymes was much lower in an anaerobic than in an aerobic atmosphere. 3. 3. Dark inactiv

1. 1. Normal males ( n = 103) excreted a greater amount of urinary porphyrins with a higher percentage of tetracarboxylic coproporphyrin and with a smaller percentage of octocarboxylic uroporphyrin than normal females ( n = 116). 2. 2. These differen

1. 1. The effects of light and porphyrins on the activity of red cell uroporphyrinogen decarboxylase were studied. 2. 2. Photoinactivation of uroporphyrinogen decarboxylase was dependent on uroporphyrin concentration, irradiation time and temperature

It has been suggested that the urinary profile of porphyrins excreted by female patients with estrogen-induced porphyria cutanea tarda is peculiar in that heptacarboxylic porphyrin equals or exceeds uroporphyrin. The chromatographic pattern of urinar
