Peroxisomal Targeting Signal - an overview

WebThe biogenesis of peroxisomes is an ubiquitin-dependent process. In particular, the import of matrix proteins into the peroxisomal lumen requires the modification of import receptors with ubiquitin. The matrix proteins are synthesized on free polyribosomes in the cytosol and are recognized by import receptors via a peroxisomal targeting sequence (PTS). ). … WebApr 12, 2024 · PV-1 was composed of merocyanine as the reporter, a HLKPLQSKL peptide chain as the peroxisomal targeting group, and a malononitrile group as the rotor.
