Shaker Voltage-Gated Potassium Channel

Below is a reconstruction of the Shaker voltage-gated potassium channel ([1]) in MRC/CCP4 format at about 25 Å resolution. The reconstruction was calculated from 6,000 images of negatively stained particles that were collected at 120 kV on a Philips CM12 electron microscope at 60,000 magnification, resulting in a pixel size of 3.5 Å.
