  1. 1 R-cells are all W3110 derivatives expressing recombinase gene at 42°C the recombinase gene is fully induced . R-cells carry the λ int expression plasmid pAH153.
  2. 2 pAH120 plasmid carrying λ attP.
  3. 3 Mean of minimum 3 trials. IF is expressed as fraction of integration frequency of parent strain, W3110.
