Movie of the tomogram of an engulfing Golgi in closed state (corresponding to Fig. 3). The first third of the movie sweeps across the computational 3.76-nm thick slices of the tomogram from the first to the last one. The second third of the movie shows the slices in the opposite direction and unravels the segmented membranes that compose the 3D model. The last third shows the model rotating 360 degrees around an axis. Colour code: Golgi cisternae in yellow, vesicles in orange, mitochondrion in cyan, lysosome in black.
