WebMar 25, 2013 · In the classic assembly pathway, the packaging motor assembles on a prohead and after head maturation and (headful) genome packaging, the motor dissociates. Then, the neck proteins, gp13, gp14, and gp15, attach to the portal sealing off the packaged head. Tail and tail fibers attach to the neck, producing an infectious virion. WebJan 31, 2024 · In headful packaging, the pac site is recognized by TerS, and the DNA is cleaved by TerL to initiate insertion into the phage head. The second cut is not dependent on a specific sequence but rather occurs once the phage head is full (Fig. 3). Therefore, provided the host DNA can be recognized and initiate packaging, the processive nature … WebThe phenomenology of bacteriophage SPP1 DNA packaging is well known and some of the molecular mechanisms involved are among the best understood in tailed phages systems.
