Effect of various C genes on the establishment of an incoming PvuII RM system. Cells carrying pYNEC126 (ecoRVC+), pYNEC130 (ecoRVC−), pYNEC311 (pvuIIC+), pYNEC401 (bamHIC+), or pIK153 (vector) were transformed with 150 ng of pYNEC300 (PvuII R+ M+ C+) or pYNEC302 (PvuII R− M+ C+). Each DNA solution contained 100 ng of pKC31 (KmR) as an internal control of the transformation efficiency. For each assay, the number of ApR transformants was divided by the number of KmR transformants. The relative transformation efficiencies are the above ratios further divided by the ratio for pIK153. The measurements were carried out in duplicate in two separate experiments.
