Overlapping homologous superfamilies

Family relationships



Protoporphyrinogen oxidase (EC: oxidises protoporphyrinogen IX to protoporphyrin IX, a precursor of haem and chlorophyll, in the penultimate step in haem and porphyrin biosynthesis. Bacillus subtilis HemY also has coproporphyrinogen III to coproporphyrin III oxidase activity in a heterologous expression system, although the role for this activity in vivo is unclear. This protein is a flavoprotein and has a beta-alpha-beta dinucleotide binding motif near the amino end.
