rph-1Strain Comments: - Δ(lacA-lacZ)880(::FRT)-- is the  DE(lacA-lacZ)879::kan deletion with the  kan cassette removed                                                                                                                                                                            
- zah-2225::FRT-- is the same as  zah-2224::cat with the  cat cassette removed                                                                                                                                                                                     
- ΔaraEp-531::kan-- has resistance marker useful for transfer of F-prime carrying Pcp- araE fusion.                                                                                                                                                                         
- rph-1-- is a 1 bp deletion that results in frameshift over last 15 codons and has polar effect on  pyrE leading to suboptimal pyrimidine levels on minimal medium.(Jensen 1993 JBact.175:3401)                                                                  
-  = kanamycin resistant
- ::FRT = Flp Recombinase Target
