The deduced amino acid sequence
(A) Homology between the deduced complete amino acid sequences of the 50 S ribosomal protein L23 of Yersinia enterocolitica O:3 (accession number for the rp/W: U11251), E. coli and Yersinia pseudotuberculosis and the archebacterium Halobacterium marismortui (Hma), respectively. Vertical lines indicate identical amino acids, (:) indicate conservative substitutions. Strong homology is present between the proteins of the three enterobacteria, and substantial homology is found to the archaebacterial analog. (B) Homology between the 50 S ribosomal protein L23 of Yersinia enterocolitica and its eucaryotic analogs, i.e., rat 60 S ribosomal protein L23a and human analog. Partial sequence alignments of the deduced amino acid sequence was performed using the TFASTA (24) program and the GENEMBL database. Vertical lines indicate identical amino acids, (:) indicate conservative substitutions. An overall identity of 36% and a similarity of 56% was found.
