Figure 2From: Multiple controls affect arsenite oxidase gene expression in Herminiimonas arsenicoxydansGenomic organization of the chromosomal regions (A, B, C and D) containing genes involved in arsenite oxidase activity. Genes orientation is shown by arrows. The insertion positions of the mini-Tn5::lacZ2 transposon are indicated above the mutated genes by inverted arrowheads. The position of the codon immediately upstream of the transposon insertion site is indicated in brackets.Back to article page
