Figure 6. Dimerization ability of the six GmPHD proteins.

Figure 6

(A) Dimerization between the GmPHD6 and other GmPHD proteins as revealed by transformant growth on YPAD and SD-His/Trp/Leu plus 3-AT, and by X-gal staining. (B) The PHD finger is not responsible for the dimerization. The yeast transformants containing pAD-GmPHD6 plus each of the PHD finger constructs or pBD vector, were examined for cell growth and X-gal staining. (C) The NV region of the GmPHD5 mediates the interaction between GmPHD5 and GmPHD6. The yeast transformants harboring the pAD-GmPHD6 plus different truncated versions of pBD-GmPHD5 were examined for cell growth and X-gal staining. Truncated proteins: GmPHD5(1–252), G5NV(1–197), G5N(1–115), G5PV(116–252), G5V(116–197), and G5PHD(198–252).
