The gene encoding ribosomal protein S11 (Escherichia coli S15 homologue) from Halobacterium marismortui was cloned employing two synthetic oligonucleotide mixtures, 23 and 32 bases in length, as hybridization probes. The nucleotide sequence of the gene and the adjacent 5'- and 3'-flanking regions (1300 base pairs) were then determined by the dideoxy chain termination method. Comparison of the nucleotide sequence of the H. marismortui S11 gene with that of the E. coli S15 gene (rpsO) showed that the 3'-end of the S11 gene can be aligned with the entire E. coli S15 gene, sharing 44% identical nucleotides. It has been found that the S11 gene has a higher G + C content (G + C = 65%) than that of the E. coli S15 gene (G + C = 53%). This increase in G + C content specifically shows up as a preference for G + C in the 3rd position of the codon. Upstream of the S11 gene, an archaebacterial promoter sequence (GGACTTTCA) and a putative ribosomal binding site (GCGGT) have been found, 88 and 15 (or 24) base pairs from the initiation codon of the gene. In addition, an open reading frame could be identified immediately after the stop codon for the S11 gene. Northern blotting analysis using the S11 coding region as probe has shown that the S11 gene is located on a 2.4-kilobase mRNA, suggesting that it is cotranscribed with other downstream gene(s).

D003001 Cloning, Molecular The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells. Molecular Cloning
D003062 Codon A set of three nucleotides in a protein coding sequence that specifies individual amino acids or a termination signal (CODON, TERMINATOR). Most codons are universal, but some organisms do not produce the transfer RNAs (RNA, TRANSFER) complementary to all codons. These codons are referred to as unassigned codons (CODONS, NONSENSE).

D012333 RNA, Messenger RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
