Figure 2.
(a) Stereo superposition of the family of 20 ETO-TAFH structures. The structure is composed of five helices, H1–H5. The longest helix, H4, is kinked by 30° owing to the presence of Pro190 in the middle of the helix. (b) Cylindrical representation of ETO-TAFH in the same orientation as in a, indicating the positions of the five helices.
