FIGURE 7.
Cross-linking of BzF-labeled BdD to SecA2 alone. The BdD variants were expressed from pCDF, and were detected by Western blotting with anti-FLAG antibodies. The amber suppression components were expressed from pEVOL-pBpF, and SecA2 was expressed from pET28c (19). Red arrow indicates BdD cross-linked to SecA2.
