II–TFIIF with nanometer precision. J. Struct. Biol. (2013).
A new, hybrid technique combines Ni-NTA-Nanogold® labeling, innovative dual-defocus imaging for single particle analysis with cryo-EM, and FRET-- achieving nanometer precision in protein architecture mapping. The group has used this powerful method to elucidate the structure and function of key components of the DNA transcription mechanism, even revealing the movement of these parts as they interact with DNA to physically initiate transcription.
