Protein

Peptidyl-prolyl cis-trans isomerase-like 1

Gene

PPIL1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 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. May be involved in pre-mRNA splicing.1 Publication

Catalytic activityi

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

Enzyme regulationi

Inhibited by Cyclosporin A.1 Publication

Kineticsi
