Structure of a flagellum and its components in various dimensions. The appropriate method for structural analysis at each scale is shown on the right. (a) Chlamydomonas cell with two flagella (5–10 µm length, 0.25 µm diameter). (b) Cross section [at the red dotted circle in (a)] of a flagellum. ODA: outer dynein arms. IDA: inner dynein arms. RS: radial spokes. (c) One microtubule doublet is extracted [red dotted circle in (b)], rotated and enlarged. (d) Schematic diagram of one dynein heavy chain [enclosed by the red dotted line in (c)]. (e) Atomic structure of the microtubule binding domain at the tip of the coiled-coil stalk. |
