What is the role of the enzyme Peptidyl Prolyl Cis/Trans Isomerase in protein metabolism?

A To catalyze the hydrolysis of peptide bonds
B To facilitate the folding of proteins by catalyzing the cis-trans isomerization of peptidyl-prolyl bonds ✓
C To synthesize new peptide bonds
D To degrade proteins into amino acids

Explanation

Peptidyl Prolyl Cis/Trans Isomerase plays a crucial role in protein folding by catalyzing the cis-trans isomerization of peptidyl-prolyl bonds, which helps in the formation of the native conformation of proteins.
