#Unit 1. Molecules and their Interaction Relevant to Biology
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?
