How Peroxisomes Receive Their Proteins

Peroxisomes receive many of their proteins from the cytoplasm and the endoplasmic reticulum. These membrane-bound organelles oxidize organic molecules by transferring hydrogen atoms to oxygen. This process produces hydrogen peroxide, which peroxisomes then break down into water and oxygen.

Peroxisomes lack DNA and cannot encode their enzymes. Peroxisomal proteins are synthesized in the ER or the cytosol and imported by peroxins, a group comprising matrix proteins, cytosolic receptors, and membrane proteins.

Peroxisomal receptors recognize the proteins by short import sequences at their C- or N-terminus called Peroxisomal Ta...
