recQ1803::Tn3Strain Comments: - The recQ::Tn3 is from strain KD1996, described by Nakayama et al. 1985. Background is W3110.
- IN(rrnD-rrnE)1-- Inverts the region between rrnD (73.74 min) and rrnE (90.66 min)
- 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)
- = ampicillin resistance
