Protein Domain : Phage P22-like portal protein IPR032427

Type  Family
Description  The portal protein of P22 and similar Podoviridae tail phages is a dodecameric structure consisting of a hip (2), a leg(1) and a barrel(3). DNA viruses such as bacteriophages and herpesviruses deliver their genome into and out of the capsid through large proteinaceous assemblies, known as portal proteins. Domains 1 and 3 are mostly helical and form the majority of the DNA-translocating channel. Domain 2 adopts an α-β-fold characterised by two sheets of eight β-strands, which cross each other to form a β-barrel-like structure [ ].
