Peptidyl Transferase

I know that peptidyl transferases works along with ribozymes and help in the formation of peptide bonds during translation. So, I am thinking that it has to be found in the ribosomes.

I am confused about this statement (from the explanations to one of the questions)

"The enzyme peptidyl transferase is responsible for the formation of peptide bonds during translation. And like the uncharged tRNA molecules, peptidyl transferase is never bound to the ribosome itself, and would only be found...
