PPOX Gene Summary [Human]

This gene encodes the penultimate enzyme of heme biosynthesis, which catalyzes the 6-electron oxidation of protoporphyrinogen IX to form protoporphyrin IX. Mutations in this gene cause variegate porphyria, an autosomal dominant disorder of heme metabolism resulting from a deficiency in protoporphyrinogen oxidase, an enzyme located on the inner mitochondrial membrane. Alternatively spliced transcript variants encoding the same protein have been identified. [provided by RefSeq, Jul 2008]

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in human PPOX often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
  • Rossmann-fold NAD(P)(+)-binding proteins
  • protoporphyrinogen oxidase
  • flavin adenine dinucleotide binding
  • NAD(P)-binding Rossmann-like domain
  • FAD dependent oxidoreductase
  • enzyme
  • protein binding
  • Flavin containing amine oxidoreductase
