WebPeptidyl-prolyl cis-trans isomerase A; PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides; Belongs to the cyclophilin-type PPIase family. PPIase A subfamily (165 aa) WebThe ubiquitous protein family peptidyl-prolyl cis/trans isomerase (PPIase) (Fischer 1994) shows a common activity in which it generally accelerates the conformational change between cis and trans of the Xaa-Pro. More than 3000 proteins in the PPIase family are classified into three subfamilies of cyclophilin, FK506-binding protein (FKBP), and parvulin …

Prolyl isomerase (also known as peptidylprolyl isomerase or PPIase) is an enzyme (EC 5.2.1.8) found in both prokaryotes and eukaryotes that interconverts the cis and trans isomers of peptide bonds with the amino acid proline. Proline has an unusually conformationally restrained peptide bond due to its cyclic … See more Proline is unique among the natural amino acids in having a relatively small difference in free energy between the cis configuration of its peptide bond and the more common trans form. The activation energy required … See more Methods for identifying the presence of a rate-limiting proline isomerization process in a protein folding event include: 1. Activation energies consistent with proline … See more • Balbach J, Schmid FX (2000). "Proline isomerizarion and its catalysis in protein folding". In Pain RH (ed.).
