Peptidyl transferase activityRibozymes are RNA molecule with catalytic activitydeg. Ribozymes play a central role in peptide bond formation peptidyl transferase activity.RibozymeRibozymes are RNA molecules with catalytic activityo.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 transferaseQ
