Comparative analysis of prophage-like elements in Helicobacter sp. genomes
Prophages are regarded as one of the factors underlying bacterial virulence, genomic diversification, and fitness, and are ubiquitous in bacterial genomes. Information on Helicobacter sp. prophages remains scarce. In this study, sixteen prophages were identified and analyzed in detail. Eight of them are described for the first time. Based on a comparative genomic analysis, these sixteen prophag...
متن کاملProfile of Eight Prophage Sequences Present in the Genomes of Different Acinetobacter baumannii Strains
ABSTRACT Background and Objective: Prophage sequences are major contributors to interstrain variations within the same bacterial species. Acinetobacter baumannii is a gram-negative bacterium that causes a wide range of nosocomial infections, especially in intensive care unit inpatients. Prophage sequences constitute a considerable proporti...
متن کاملStructure and function of RNA elements present in enteroviral genomes.
Enteroviruses are small RNA(+) viruses that encode one open reading frame flanked by two extensive noncoding regions carrying structural RNA regulatory elements that control replication and translation processes. For a long time the central, coding region was thought to remain single-stranded and its only function was supposed to be as the template for polyprotein synthesis. It turned out, howe...
متن کاملComprehensive analysis of endogenous bornavirus-like elements in eukaryote genomes.
Bornaviruses are the only animal RNA viruses that establish a persistent infection in their host cell nucleus. Studies of bornaviruses have provided unique information about viral replication strategies and virus-host interactions. Although bornaviruses do not integrate into the host genome during their replication cycle, we and others have recently reported that there are DNA sequences derived...
متن کاملTranscription termination controls prophage maintenance in Escherichia coli genomes.
Prophages represent a large fraction of prokaryotic genomes and often provide new functions to their hosts, in particular virulence and fitness. How prokaryotic cells maintain such gene providers is central for understanding bacterial genome evolution by horizontal transfer. Prophage excision occurs through site-specific recombination mediated by a prophage-encoded integrase. In addition, a rec...
