During the late stages of lambda bacteriophage assembly, the protein gpU terminates tail polymerization and participates at the interface between the mature capsid and tail components. When it engages the lambda tail, gpU undergoes a monomer-hexamer transition to achieve its biologically active form. Towards understanding how gpU participates in multiple(More)
The tail terminator protein (TrP) plays an essential role in phage tail assembly by capping the rapidly polymerizing tail once it has reached its requisite length and serving as the interaction surface for phage heads. Here, we present the 2.7-A crystal structure of a hexameric ring of gpU, the TrP of phage lambda. Using sequence alignment analysis and(More)
