Strain Comments:

• From the Keio Collection of single-gene knockouts constructed through a collaboration of the Inst. of Adv. Biosci. at Keio Univ., the Nara Inst. of Sci and Technol., Japan and Purdue Univ., USA
• Δ(araD-araB)567-- This deletion extends from ~25 bp upstream of the araB start codon to ~8 bp into the beginning of the araD gene
• ΔlacZ4787(::rrnB-3)-- : 4 tandem copies of the rrnB transcriptional terminator inserted by gene replacement into the region extending from near the SacII site near the N-terminus of lacZ through the promoter.
• 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)
• ΔpldB770::kan-- The primers used to make this knockout were CAGACGCAACAACCTGGTACATAAGAAATTTAAACCTCTGTAGAGCGGTTATTCCGGGGATCCGTCGACC and CACGCTAAAAAAAACGATTTTACGTGGTTTAAGAGGCAGATTACCCGATGTGTAGGCTGGAGCTGCTTCG the bolded sequence matches the pKD13 template
• Δ(araD-araB)567 was formerly called Δ araBAD_AH33
• Δ(rhaD-rhaB)568 was formerly called Δ rhaBAD_LD78
• ΔlacZ4787(::rrnB-3) was formerly called ::rrnB-4
• ΔlacZ4787(::rrnB-3) was formerly called Δ lacZ_WJ16
• = kanamycin resistant
• ::rrnB-3 = 4 copies of rrnB inserted
