Peptidyl-prolyl cis/trans isomerases in GtoPdb v.2021.2
Abstract
Peptidyl-prolyl cis/trans isomerases (PPIases) are an enzyme family which catalyse the cis/trans isomerisation of proline peptide bonds to promote the folding and re-folding of peptides and proteins. Three subfamilies have been identified: cyclophilins, FK506-binding proteins and parvulins. Individual PPIases are overexpressed in a number of cancers [59], and family members have been targetted for immunosuppressant effects.
