MeSH definition : An enzyme that catalyzes the decarboxylation of UROPORPHYRINOGEN III to coproporphyrinogen
III by the conversion of four acetate groups to four methyl groups. It is the fifth
enzyme in the 8-enzyme biosynthetic pathway of HEME. Several forms of cutaneous PORPHYRIAS
are results of this enzyme deficiency as in PORPHYRIA CUTANEA TARDA; and HEPATOERYTHROPOIETIC
PORPHYRIA.;
