Abstract：
:Protoporphyrinogen oxidase (EC 1.3.3.4) is the penultimate enzyme in the heme biosynthetic pathway, catalyzing the six-electron oxidation of protoporphyrinogen to protoporphyrin. A dominantly inherited genetic deficiency in this enzyme results in the disease variegate porphyria. We now report the cloning, sequence, and expression of mouse protoporphyrinogen oxidase. The cDNA for mouse protoporphyrinogen oxidase was obtained by complementation of Escherichia coli SASX38, a protoporphyrinogen oxidase-deficient strain, with a mouse erythroleukemia (MEL) cell expression library. The sequence of this cDNA along with 5' untranslated sequence obtained by 5' rapid amplification of cDNA ends of MEL cell mRNA is 1814 bp in length and contains an open reading frame of 1431 bp. This encodes a protein of 477 amino acid residues with a calculated molecular weight of 50,870. The protein as expressed in E. coli is sensitive to inhibition by the diphenyl ether herbicide acifluorfen. Northern blot analyses of RNA from uninduced and induced MEL cells as well as mouse hepatoma cells all show two major mRNA species of 1.8 and 3.6 kb.
