Figure 5From: The solution structure of ChaB, a putative membrane ion antiporter regulator from Escherichia coliComparison of ChaB with structurally similar proteins. Structural similarities between (A) ChaB, (B) σ70(PDB code 1SIG [14]) and (C) σRN (PDB code 1H3L, [15]) proteins identified from the DALI server. The three helices in ChaB are colour coded, with the equivalent helices in σ70 and σRN similarly coloured.Back to article page
