1zku is a 18 chain structure with sequence from Escherichia virus T4. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
BP09_BPT4 Baseplate protein that connects the long tail fibers to the baseplate and probably triggers the tail contraction after virus attachment to a host cell (PubMed:10545330). Involved in the tail assembly (PubMed:21129200).[1][2]
