'''PRD1 vertex protein P5'''<br />


==Overview==
==PRD1 vertex protein P5==
Comparisons of bacteriophage PRD1 and adenovirus protein structures and, virion architectures have been instrumental in unraveling an evolutionary, relationship and have led to a proposal of a phylogeny-based virus, classification. The structure of the PRD1 spike protein P5 provides, further insight into the evolution of viral proteins. The crystallized P5, fragment comprises two structural domains: a globular knob and a fibrous, shaft. The head folds into a ten-stranded jelly roll beta barrel, which is, structurally related to the tumor necrosis factor (TNF) and the PRD1 coat, protein domains. The shaft domain is a structural counterpart to the, adenovirus spike shaft. The structural relationships between PRD1, TNF, and adenovirus proteins suggest that the vertex proteins may have, originated from an ancestral TNF-like jelly roll coat protein via a, combination of gene duplication and deletion.

== Publication Abstract from PubMed ==
Comparisons of bacteriophage PRD1 and adenovirus protein structures and virion architectures have been instrumental in unraveling an evolutionary relationship and have led to a proposal of a phylogeny-based virus classification. The structure of the PRD1 spike protein P5 provides further insight into the evolution of viral proteins. The crystallized P5 fragment comprises two structural domains: a globular knob and a fibrous shaft. The head folds into a ten-stranded jelly roll beta barrel, which is structurally related to the tumor necrosis factor (TNF) and the PRD1 coat protein domains. The shaft domain is a structural counterpart to the adenovirus spike shaft. The structural relationships between PRD1, TNF, and adenovirus proteins suggest that the vertex proteins may have originated from an ancestral TNF-like jelly roll coat protein via a combination of gene duplication and deletion.
