Figure 23-7: The pac region of bacteriophage SPP1. The black bar indicates 399 bp of the SPP1 sequence containing the packaging initiation region. The enlarged regions pacL and pacR are recognized by the terminase small subunit (G1P) and are the non encapsidated left end and the encapsidated right end, respectively, of the SPP1 sequence. pacC is the packaging processing site. The open boxes labeled a, b, and c indicate repeated sequences in the pac region. The arrows indicate the staggered nicks in the 10 bp repeat boxes within pacC introduced by the terminase large subunit (G2P).
