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

Which of the following combinations is correct about protein folding pathways?
