Details of the T4 baseplate structure; reprinted from [5]. Proteins are labeled with their respective gene numbers. A, The garland of short tail fibers gp12 (magenta) with gp11 structures (light blue C_α trace) at the kinks of the gp12 fibers. The six-fold axis of the baseplate is shown as a black line. B, The baseplate "pins", composed of gp7 (red), gp8 (dark blue C_α trace), gp10 (yellow), and gp11(light blue C_α trace). Shown also is gp9 (green C_α trace), the long tail fiber attachment protein, with a green line along its three-fold axis, representing the direction of the long tail fibers. C, Gp6, gp25, and gp53 density.
