CC   -!- FUNCTION: PPIases accelerate the folding of proteins. It catalyzes the
CC       cis-trans isomerization of proline imidic peptide bonds in
CC       oligopeptides (By similarity). {ECO:0000250}.
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: Inhibited by cyclosporin A (CsA). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Endoplasmic reticulum lumen {ECO:0000255|PROSITE-
CC       ProRule:PRU10138}.
CC   -!- SIMILARITY: Belongs to the cyclophilin-type PPIase family. PPIase B
CC       subfamily. {ECO:0000305}.
