Comments
  • FUNCTION: Prolyl cis/trans isomerase with specificity for phospho-Ser-Pro bonds.
  • CATALYTIC ACTIVITY: Peptidylproline (omega=180) = peptidylproline (omega=0).
  • ENZYME REGULATION: Inhibited in vitro by juglone.
  • SUBCELLULAR LOCATION: Cytoplasm. Nucleus.
  • TISSUE SPECIFICITY: Expressed in roots, stems, leaves, flowers and seedlings.
  • PTM: The N-terminus is blocked.
  • MISCELLANEOUS: Like all plant Pin1-type PPIases, do not contain the N-terminal WW domain found in other eukaryotic parvulins, but contains a four-amino acid insertion next to the phospho-specific recognition site of the active site. These extra amino acids may be important for mediating the substrate interaction of plant enzymes.
  • MISCELLANEOUS: Three amino acid residues (P79S, E91D and A95G) differ when compared with the partial sequence of purified protein. The existence of two or more genes coding for this protein is not exluded.
  • SIMILARITY: Belongs to the ppiC/parvulin rotamase family.
  • SIMILARITY: Contains 1 PpiC domain.
