Peptidyl-prolyl cis-trans isomerase E <p>This group represents peptidyl-prolyl cis-trans isomerase E, also known as cyclophilin. This enzyme can accelerate the folding of proteins by catalysing the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. It also posses RNA-binding activity and may be involved in pre-mRNA splicing [<cite idref="PUB00044695"/>, <cite idref="PUB00044696"/>].</p>
