  1. This includes contacts suggested by others as being part of the extant center, with the 23S RNA contacting bases conserved, at least 90%. In the case of L10e, L44e and L15e the amino acid conservation is only across Archaea and Eukarya as indicated by the dash. The bacterial L16, L31 and L33 structures are not at a high enough resolution to attempt to identify equivalent contacts with such divergent sequences and structures. The notation otherwise is the same as in Table 1.
