| + | [https://www.uniprot.org/uniprot/TIPJ_LAMBD TIPJ_LAMBD] Attaches the virion to the host receptor LamB, inducing viral DNA ejection. During tail assembly, initiates distal tail tip assembly by interacting with gpI, gpL and gpK. During virus entry to host cell, binds strongly to host LamB in an irreversible attachment. The binding induces structural changes in the tail leading to viral DNA injection through LamB trimeric pore.<ref>PMID:6228546</ref> | ||

| + | Bacteriophage infection, a pivotal process in microbiology, initiates with the phage's tail recognizing and binding to the bacterial cell surface, which then mediates the injection of viral DNA. Although comprehensive studies on the interaction between bacteriophage lambda and its outer membrane receptor, LamB, have provided rich information about the system's biochemical properties, the precise molecular mechanism remains undetermined. This study revealed the high-resolution cryo-electron microscopy (cryo-EM) structures of the bacteriophage lambda tail complexed with its irreversible Shigella sonnei 3070 LamB receptor and the closed central tail fiber. These structures reveal the complex processes that trigger infection and demonstrate a substantial conformational change in the phage lambda tail tip upon LamB binding. Providing detailed structures of bacteriophage lambda infection initiation, this study contributes to the expanding knowledge of lambda-bacterial interaction, which holds significance in the fields of microbiology and therapeutic development. | ||
