| Listeria monocytogenes can cause serious infection and recently, relapse of listeriosis has been reported in leukemia and colorectal cancer, and the patients with Klebsiella pneumoniae are at increased risk of colorectal cancer. Translation initiation codon recognition is basically mediated by Shine-Dalgarno (SD) and the anti-SD sequences at the small ribosomal RNA (ssu rRNA). In this research, Shine-Dalgarno sequences prediction in Listeria monocytogenes La111 and Klebsiella pneumoniae KCTC 2242 was investigated. The whole genomic sequence of Listeria monocytogenes La111 and Klebsiella pneumoniae KCTC 2242 were retrieved from http://www.ncbi.nlm.nih.gov/ (Listeria monocytogenes La111 NCBI Reference sequence: NC_020557 Klebsiella pneumoniae KCTC 2242 NCBI Reference sequence: CP002910) in order to be analyzed with DAMBE software and BLAST. The results showed that the consensus sequence for Klebsiella pneumoniae KCTC 2242 was CCCCCCCUCCCCCUCCCCCUCCUCCUCCUUUUUAAAAAAGGGGAAAAACC and for Listeria monocytogenes La111 was CCCCCCCUCCCCCUUUCCCUCCUAUUCUUAUAAAAGGGGG-GGGGUUCAC. The PSD was higher in Listeria monocytogenes La111 compared to Klebsiella pneumoniae KCTC 2242 (0.9090> 0.8618). The results showed that Nm in Listeria monocytogenes La111 was higher than Klebsiella pneumoniae KCTC 2242 (4.5846> 4.4862). Accurate characterization of SD sequences may increase our knowledge on how an organism’s transcriptome is related to its cellular proteome. |
