Figure 6From: A new suite of tnaA mutants suggests that Escherichia coli tryptophanase is regulated by intracellular sequestration and by occlusion of its active site Altered localization of TnaA and D1D3 variants. Images of altered localization, one representative variant from each subgroup in Table 2. The TnaA variants are shown in A, C and E, and their corresponding D1D3 variants are shown in B, D and F. The cells were grown in LB for 2.5 or 3 h (OD600 ~ 0.6 and 1.0, respectively).Back to article page
