Chimeric GCN4 fusions with 450K and 450KR. (A) Design of the GCN4-450 fusions. The heptad repeats from a to g were built from the registry of GCN4 and the adapters. GCN4 enforces the hydrophobic ad interface (shown in bold), and shifts the registry of the heptads of kinase coiled-coil according to the different adapters. The predicted position of His474 (*in the K domain) in each fusion is shown at the end of the sequence. (B) A. tumefaciens strain A136 carrying pRG109 and the indicated GCN4-450KR fusions were assayed for vir gene expression without inducers. The degree of rotation created by each fusion is shown in the figure with the 0° rotation defined at LZ(0)-450. The protein expression of the GCN4-450KR constructs was analyzed by Western blot.
