Abstract
A method for treatment or prophylaxis of disease caused by deficiency, in a subject, of an enzyme belonging to the heme biosynthetic pathway, the method comprising administering, to the subject, an effective amount of a catalyst which is an enzyme or an enzymatically equivalent part or analogue thereof. The disease is selected from the group consisting of acute intermittent porphyria (AIP), ALA deficiency porphyria (ADP), Porphyria cutanea tarda (PCT), Hereditary coproporphyria (HCP), Harderoporphyria (HDP), Variegata prophyria (VP), Congenital erthropoetic porphyria (CEP), Erythropoietic protoporphyria (EPP), and Hepatoerythropoietic porphyria (HEP). The catalyst is one or more enzymes selected from the group consisting of delta-aminolevulininic acid synthetase, delta-aminolevulinic acid dehydratase (ALAD), porphobilinogen deaminase (PBGD), uroporphyrinogen III cosythetase, uroporphyrinogen decarboxylase, coproporphyrinogen oxidase, protoporphyrinogen oxidase, and ferrochelatase, or an enzymatically equivalent part or analogue thereof. In addition the invention relates to the use of PBGD, to human recombinant PBGD and to a method of gene therapy. The invention also relates to an expression plasmid pExp1-M2-BB (Seq. ID No. 1) and to use of a DNA fragment, the EcoRI-Hind III linear fragment (seq. ID No. 2), used for transformation in the hemC disruption strategy for production of rhPBGD expressed in
