1 The residues listed are based on the 70S crystal structure (Yusupov et al., 2001) and are listed with E. coli numbering.

2 Residue(s) universally or highly conserved, but one of the residues is conserved as a position (less than 90% at the nucleotide level, but position is present in at least 95% of the sequences).

3 Residue(s) position(s) conserved in at least 95% of the sequences, but conservation is not greater than 90% at the nucleotide level.

4 One of the residues in this region is not conserved.
