Protein
Peptidyl-prolyl cis-trans isomerase Pin1
Gene
PIN1
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Functioni
Prolyl cis/trans isomerase with specificity for phospho-Ser-Pro bonds.1 Publication
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.
Catalytic activityi
Peptidylproline (omega=180) = peptidylproline (omega=0).
