Organization and nucleotide sequence of a new ribosomal operon in Escherichia coli containing the genes for ribosomal protein S2 and elongation factor Ts.


We report the nucleotide sequence of the four min region of the Escherichia coli genetic map that includes the genes for ribosomal protein S2 (rpsB) and translation elongation factor EF-Ts (tsf), and the possible location of regulatory sites within this two gene operon. The data indicate that the gene order is: rpsBp-rpsB-tsf-tsft. One potential regulatory site is a 16 nucleotide sequence in the rpsB leader region encompassing the ribosome binding site and the translation initiation codon. This has a high degree of homology with nucleotides 8 through 23 on the 5' end of 165 ribosomal RNA, and might signify a sequence that is necessary for post-transcriptional control of rpsB expression. The data allow one to infer the amino acid sequences of S2 and EF-Ts.
