WebJan 3, 1998 · Fe-coproporphyrin III + 2 H (+) + 2 H2O2 <=> 2 CO2 + 4 H2O + heme b Comment (s) The enzyme participates in a heme biosynthesis pathway found in Gram- positive bacteria. The initial decarboxylation step is fast and yields the three- propanoate harderoheme isomer III. The second decarboxylation is much slower, cf. EC 1.3.98.6 . … WebUrinary and fecal coproporphyrin is mostly type III. Urinary ALA, PBG, and uroporphyrins are increased during acute attacks but may be normal or only slightly increased during remission. ALA and PBG may be less elevated and return to normal more rapidly in VP and HCP than in AIP.
