Chromosomal Markers: lacZ4817,
mhpC281::Tn10,
λ-,
ΔmutS738::kan,
rph-1Strain Comments: - lacZ4817-- is a single basepair insertion of an A residue causing a frameshift mutation at base 1570 in the lacZ gene.
- mhpC281::Tn10-- cotransduces 80% with lac.
- ΔmutS738::kan-- The primers used to make this knockout were AAAAACCATCACACCCCATTTAATATCAGGGAACCGGACATAACCCCATGATTCCGGGGATCCGTCGACC and CGATAGCAAAAGACTATCGGGAATTGTTATTACACCAGGCTCTTCAAGCGTGTAGGCTGGAGCTGCTTCG the bolded sequence matches the pKD13 template
- 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)
- lacZ4817 was formerly called lacZ(-1A1570)
- mhpC281::Tn10 was formerly called zah281::Tn10
- = tetracycline resistant
- = kanamycin resistant
