Figure 1

Domain structure of CRE1/AHK4 and secondary structure prediction of the CHASE domain. (A) The domain structure of the full-length protein and different truncated versions of CRE1/AHK4 used in this study. (B) The predicted secondary structure of the CHASE domain with the amino acid substitutions tested in the cytokinin binding assay marked in red. White tubes represent α-helices and grey areas β-sheets. Secondary structure prediction was done by PSIPred v2.4 [43]. Abbreviations: CHASE, cyclases, histidine kinase associated sensory extracellular; HisKA, histidine kinase A domain; HATPase, histidine kinase-like ATPase; Rec, receiver domain; Tmds, transmembrane domains.
