1if0 is a 7 chain structure with sequence from Escherichia virus HK97. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
CAPSD_BPHK7 Assembles to form an icosahedral capsid of 66 nm, with a T=7 laevo symmetry (PubMed:11000116, PubMed:21276801). Responsible for its self-assembly into a procapsid. The phage does not need to encode a separate scaffolfing protein because its capsid protein contains the delta domain that carries that function.[1][2][3][4]
