Structural highlights
1kvp is a 1 chain structure with sequence from Escherichia virus phiX174. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
CAPSD_BPPHS Assembles to form an icosahedral capsid with a T=1 symmetry, about 30 nm in diameter, and consisting of 60 capsid proteins F (PubMed:11991963, PubMed:1370343, PubMed:8158636). Upon virus binding to host cell, one of the spikes dissociates from the capsid and the virus interacts with LPS through the exposed EF loops on the F proteins (PubMed:29229840). After the genome had been ejected, the channel formed by the F proteins at the unique fivefold axis remains open (PubMed:29229840).[1][2][3][4]
