The abstract theory governing ribozyme catalysis in rRNA during protein synthesis defines the molecular mechanism wherein the 23S/18S ribosomal RNA component, functioning intrinsically without auxiliary enzymes, facilitates peptide bond formation via peptidyl transferase activity. This process operates within the structural framework of the large and small ribosomal subunits (60s/40s in eukaryotes), where specific sites—the A site for aminoacyl-tRNA entry, the P site for peptidyl-tRNA accommodation, and the exit pathway—orchestrate the transfer of nascent polypeptide chains. The fundamental principle establishes that ribosomal RNA serves as a biologically significant ribozyme, mediating the translation of genetic information encoded in mRNA into functional protein structures through precise spatial arrangement within cytoplasmic or organelle-specific ribosomes.
