Comparison of module I to response regulators from bacteria. (A) Multiple alignment of module I from plants and response regulators from bacteria. Ec, Escherichia coli CheY; Bs, Bacillus subtilis SPO0F. The lineup is as described in Figure 2. (B) Structures of the Arabidopsis model for module I and published structures for two response regulators (left) and aligned with to Arabidopsis module I (right). Coloration is as shown.
