- Name: topA75(del)
- Type: Deletion
- Mutation of Gene: topA
- Approx. Map Location: 28.65
Property Symbol deletion del
- : Strains can rapidly lose the phenoytpe by accumulation of secondary mutations. It may be necessary to transduce topA75 zci-2234::cat into MG1655 (or other) to observe phenotype.
- deletes the promoter and the N-terminal part of TopI. It is able to grow normally at 42C, but at 30C with small inoculum, it grows poorly, no colonies are visible after 24 hr..
