A comparison of triples in four 23S rRNA structures available ( H. marismortui , D. radiodurans , E. coli , T. thermophilus ; PDB: 1ffk, 1nkw, 2awb, 2j01 respectively) and using the H. marismortui str... cture as a reference, shows that 21 out of the 28 triples are also conserved in the other three structures.
These include a triple [C2104.A2485.C2536; PDB: 1ffk] [ 1 ] that was also found to be structurally conserved in the structural alignments and is also conserved in all the sequences aligned.
Structural comparisons of T. thermophilus [PDB: 2j01], E. coli [PDB: 2awb] and D. radiodurans [PDB: 1nkw] to the H. marismortui [PDB: 1ffk] structure were carried out using least squares superposition on the phosphate backbone atoms by the program LSQKAB [ 21 ] from the CCP4 suite [ 22 ].
