Protein

Peptidyl-prolyl cis-trans isomerase E

Gene
N/A
Organism
Schistosoma mansoni (Blood fluke)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides.

Catalytic activityi

Peptidylproline (omega=180) = peptidylproline (omega=0).

Enzyme regulationi

Binds cyclosporin A (CsA). CsA mediates some of its effects via an inhibitory action on PPIase.
