From: The transition from noncoded to coded protein synthesis: did coding mRNAs arise from stability-enhancing binding partners to tRNA?

Figure 2

Our proposal for the origin of coded protein synthesis. A depiction of the ancestral peptidyl transferase ribozyme as proposed by Bokov and Steinberg [9] with two tRNAs and a serendipitous proto-mRNA binding partner bound to the two tRNA anticodon loops. Adapted from the PDB files of the T. thermophilus 70S ribosome (with tRNAs and mRNA) taken from Voorhees et al. [98]. PDB files rendered using MacPyMol [99].
