Protoporphyrinogen oxidase or protox is an enzyme that in humans is encoded by the PPOX gene. Protoporphyrinogen oxidase is responsible for the seventh step in biosynthesis of protoporphyrin IX. This porphyrin is the precursor to hemoglobin, the oxygen carrier in animals, and chlorophyll, the dye in plants. The enzyme catalyzes the dehydrogenation (removal of hydrogen atoms) of protoporphyrinogen IX (the product of the sixth step in the production of heme) to form protopor… Webb13 apr. 2024 · Amaranthus retroflexus L. is a highly competitive broadleaf weed of corn–soybean rotation in northeastern China.
