Genomic characterization provides new insight into Salmonella phage diversity

Phage evolution: New worlds of genomic diversity

A recent comparative survey of genomes of phages infecting mycobacteria reveals a vast combinatorial network of gene rearrangements and may provide general models for pattern and process in genome evolution.

Genomic organization of the crested ibis MHC provides new insight into ancestral avian MHC structure

The major histocompatibility complex (MHC) plays an important role in immune response. Avian MHCs are not well characterized, only reporting highly compact Galliformes MHCs and extensively fragmented zebra finch MHC. We report the first genomic structure of an endangered Pelecaniformes (crested ibis) MHC containing 54 genes in three regions spanning ~500 kb. In contrast to the loose BG (26 loci...

Mitophagy: New Insight into the Cardiovascular Aging  

Genomic and proteomic characterization of the broad-host-range Salmonella phage PVP-SE1: creation of a new phage genus.

(Bacterio)phage PVP-SE1, isolated from a German wastewater plant, presents a high potential value as a biocontrol agent and as a diagnostic tool, even compared to the well-studied typing phage Felix 01, due to its broad lytic spectrum against different Salmonella strains. Sequence analysis of its genome (145,964 bp) shows it to be terminally redundant and circularly permuted. Its G+C content, 4...

A DNA structural alphabet provides new insight into DNA flexibility

DNA is a structurally plastic molecule, and its biological function is enabled by adaptation to its binding partners. To identify the DNA structural polymorphisms that are possible in such adaptations, the dinucleotide structures of 60 000 DNA steps from sequentially nonredundant crystal structures were classified and an automated protocol assigning 44 distinct structural (conformational) class...
