CC -!- FUNCTION: PPIases accelerate the folding of proteins. It catalyzes the
CC cis-trans isomerization of proline imidic peptide bonds in
CC oligopeptides.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[protein]-peptidylproline (omega=180) = [protein]-
CC peptidylproline (omega=0); Xref=Rhea:RHEA:16237, Rhea:RHEA-
CC COMP:10747, Rhea:RHEA-COMP:10748, ChEBI:CHEBI:83833,
CC ChEBI:CHEBI:83834; EC=5.2.1.8;
CC -!- ACTIVITY REGULATION: Binds cyclosporin A (CsA). CsA mediates some of
CC its effects via an inhibitory action on PPIase.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the cyclophilin-type PPIase family.
CC {ECO:0000305}.
CC -!- CAUTION: Was originally (PubMed:1623198) reported to be isolated from
CC an A.thaliana cDNA library. PubMed:9426607 authors have assigned that
CC the sequence has been amplified from an other contaminating organism.
CC {ECO:0000305|PubMed:1623198}.
