Comparative analysis of prophages in Streptococcus mutans genomes
Prophages have been considered genetic units that have an intimate association with novel phenotypic properties of bacterial hosts, such as pathogenicity and genomic variation. Little is known about the genetic information of prophages in the genome of Streptococcus mutans, a major pathogen of human dental caries. In this study, we identified 35 prophage-like elements in S. mutans genomes and p...
متن کاملOn Base-Pairing Potential Between 16S rRNA and 5’ UTR in Archaebacterial Genomes
The Shine-Dalgarno (SD) sequence [4] of E. coli is known to be a signal to initiate translation. The widely accepted model is that the 3’ end of 16S rRNA base-pairs with the SD sequence in the first step of ribosome binding to mRNA. However, archaebacteria have been supposed to have systems of translation different from those of eubacteria and eucaryotes. Further, some eubacteria, such as M. ge...
متن کاملOn Negative Selection Against ATG Triplets Near Start Codons in Archaebacterial Genomes
Translation initiation mechanisms in eubacteria and eukaryotes are quite different. In eubacteria, ribosome binds directly to the Shine-Dalgarno sequence located several bases upstream of the start codon. In eukaryotes, on the other hand, ribosome binds to the CAP structure located at the 5’ end of mRNA, and scans the mRNA until it finds the start codon. However, the translation initiation mech...
متن کاملIdentification of Prophages in Bacterial Genomes by Dinucleotide Relative Abundance Difference
BACKGROUND Prophages are integrated viral forms in bacterial genomes that have been found to contribute to interstrain genetic variability. Many virulence-associated genes are reported to be prophage encoded. Present computational methods to detect prophages are either by identifying possible essential proteins such as integrases or by an extension of this technique, which involves identifying ...
متن کاملGenomes of Gardnerella Strains Reveal an Abundance of Prophages within the Bladder Microbiome
Bacterial surveys of the vaginal and bladder human microbiota have revealed an abundance of many similar bacterial taxa. As the bladder was once thought to be sterile, the complex interactions between microbes within the bladder have yet to be characterized. To initiate this process, we have begun sequencing isolates, including the clinically relevant genus Gardnerella. Herein, we present the g...
