Dynein conformation in flagella. (a) Averaged tomogram utilizing 96 nm periodicity. Light blue: outer dynein arms. Red: inner dynein arms. Grey: microtubule doublet. (b) Molecular arrangement of dynein isoforms revealed by tomographic analysis of wild-type and mutant Chlamydomonas flagella. Modified from Bui et al. (2009). (c) Structure of inner arm dynein c before the power stroke. (d) As for (c) but after the power stroke. In (c) and (d), dyneins c and e are labeled. (e) Schematic representation of the power stroke. Left: proximal (−) end. Right: distal (+) end. Modified from Movassagh et al. (2010). |
