Figure 4From: A single amino acid change within the R2 domain of the VvMYB5b transcription factor modulates affinity for protein partners and target promoters selectivityVvMYB5bL loses its ability to physically interact with the bHLH transcription factor VvMYC1 in yeast. Yeast two-hybrid experiments have been performed by co-transformation with VvMYB5bR or VvMYB5bL proteins fused to GAL4 Activation Domain, and VvMYC1 fused to GAL4 DNA Binding Domain. Transformed yeasts were selected on SD-Leu-Trp- medium and tested for LacZ activation. β-Galactosidase activity results are the mean of three measurements of three independent yeast clones. Negative two-hybrid control refers to the control provided by the manufacturer. Error bars indicate SD.Back to article page
