attP22BStrain 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
- 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)
- Δ(araD-araB)567 was formerly called Δ araBADAH33

- ΔlacZ4787(::rrnB-3) was formerly called ::rrnB-4
- ΔlacZ4787(::rrnB-3) was formerly called Δ lacZWJ16
- ::rrnB-3 = 4 copies of rrnB inserted
