Pac2 12,058 4,300/6,200/10,250
Pac3 11,151 6,900

  1. For Pac2, there are three candidate locations for Ori, all of which are characterized by abrupt changes in base composition bias and significant stem-loop configurations; however, only the Ori at position 4,300 is also characterized by repeats.
