The folding pathways of some proteins require two enzymes that catalyze isomerization reactions such as,
a) Peptide prolyl isomerase (PPI) catalyzes the elimination of folding intermediates with inappropriate disulfide cross-links
b) Protein disulfide isomerase (PDI) enzyme that catalyzes the interchange, or shuffling, of disulfide bonds until the bonds of the native conformation are formed
c) Peptide prolyl cis-trans isomerase (PPI) catalyzes the interconversion of the cis and trans isomers of Proline residue peptide bonds
d) Peptide prolyl isomerase (PPI) can be a fast step in the folding of proteins that contain some Pro peptide bonds in the cis conformation
