Abstract:
The dsDNA of Listeria bacteriophages A006, A500, A511, B025, B054, and P35 were sequenced and analysed regarding G+C content, open reading frames, tRNA genes and sequence identities on nucleotide and protein level. Additionally, bacterial integration sites for the temperate phages were identified. Genes are arranged into functional, life-cycle specific modules. The mosaic nature of the genomes supports the modular evolution theory and provides insight into the phylogenetic relationship among the Listeria phages. Analysis of the structural proteins via peptide mass fingerprinting allowed a correlation between predicted gene products and protein bands from the profiles (SDS-Page) and indicated translational frameshifts during synthesis of the major capsid and major tail proteins in some phages.
