'''PRD1 vertex protein P5'''

== Function ==

[https://www.uniprot.org/uniprot/P5_BPPRD P5_BPPRD] In association with P31 and P2, forms the spike complexes located at the 5-fold vertices of the capsid. Essential for viral infectivity.<ref>PMID:10956048</ref>

==Overview==
+
== 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.
