Wild-type and chimeric module systems designed to probe the specificity of each AT from PikAIII and PikAIV. R1 is the wild-type PikAIII (red) and wild-type PikAIV (purple) with the native PikAIV TE (blue). AT swaps were used to create R2 and R3 from R1. R4 is PikAIII fused to the PikAIV TE. Each Pik AT was swapped into Ery6TE (R6, grey) to generate R7 and R8.
