hsdR514Strain Comments: - 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
- 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)
- Δ(araD-araB)567 was formerly called Δ araBADAH33
- Δ(rhaD-rhaB)568 was formerly called Δ rhaBADLD78
- = kanamycin resistant
