Figure S2. Rotary metal shadowing EM images of Myo2p-GFP and Myo4p-GFP. Field views show many clear images of two-headed Myo2p-GFP, but few of Myo4p-GFP. Quantitation of several fields of Myo2p-GFP and Myo4p-GFP revealed densities of images of two-headed motors at 3.8/µm2 and 0.4/µm2, respectively.
