Peptidyl transferase activity Ref: Harper 28e p364; 27e p364; Lippincott 4e p435-439; Lehninger 5e p1078Ribozymes are RNA molecule with catalytic activityQ. Ribozymes play a central role in peptide bond formation peptidyl transferase activity.RibozymeRibozymes are RNA molecule with catalytic activityQ.These generally involve transesterification reactions, and most are concerned with RNA metabolism splicing and endoribonuclease.Recently, a ribosomal RNA component was noted to hydrolyze an aminoacyl ester and thus play a central role in peptide bond formation peptidyl transferase Q.
