Each of the two ribosomal subunits contains many different proteins.
In contrast, signatures that result from recombination between ribosomal variants leave traces that defy any phylogenetic hypothesis.
Phylogenetic relationship of organisms obtained by ribosomal protein comparison.
Direct cross-links between initiation factors 1, 2, and 3 and ribosomal proteins promoted by 2-iminothiolane.
The tree is a summary of data from two gene regions, the mitochondrial cox1 gene and the nuclear second ribosomal internal transcribed spacer.
These findings suggest that general acid-base catalysis by ribosomal residues does not play a significant role in peptidyl transfer on the ribosome.
