Two Myo4p–She3p motor complexes bind per She2p tetramer. (A) A field of metal-shadowed images of Myo4p–She3p alone. (B) A field of metal-shadowed images of Myo4p–She3p in the presence of She2p. Note the prevalent V-shaped structures, which show that two motor complexes bind per She2p tetramer. (C) Gallery of Myo4p–She3p alone. (D) Gallery of images showing two Myo4p–She3p motors bound to the She2p tetramer.
