From: Divergence of the mRNA targets for the Ssb proteins of bacteriophages T4 and RB69
A comparison between the genetic maps of the Ssb protein (gp32) encoding regions of phages T4 and RB69. Note the presence of an open-reading frame (ORF) for a homing endonuclease (SegG protein; [45]) between T4 genes 59 (gp59; primase-helicase loader) and 32 (gp32; Ssb protein). The restriction sites we used for cloning RB69 gene 32 are marked, and compared to the locations of analogous sites in T4. GenBank Accession numbers for the genetic regions of interest are also noted.
