sodA25::MudIIPR13Strain Comments: - Δ(argF-lac)169-- extends from mmuP through orfs preceding argF, through lac to mhpD, literally Δ(mmuP-mhpD)169. (Peters et al. 2003 JB 185:2017)
- Δ(argF-lac)169-- from strain Hfr3000 U169 was initially called ΔlacU169 and described as a lacZY mutation until found to include argF and lacI.
- IN(rrnD-rrnE)1-- Inverts the region between rrnD (73.74 min) and rrnE (90.66 min)
- -$\Delta$2 = {\it sodB Tn9} deletion
