Figure 6. Combination of difference maps.

Figure 6

Density from difference maps (Figure 3) isolating the connector (green), pRNA (magenta) and ATPase (blue) were combined to visualize the DNA packaging motor in ϕ29.

(A) End-on view of the motor, looking from the pRNA down the long axis of the phage.

(B), Cut-away of side view of the motor, with the front half of the motor density removed.

(C) Cut-away of side view of the motor, with the front half of the motor density removed and the structure of DNA placed in the central channel of the packaging motor.

(D).The motor is shown in the context of the entire prohead. The front half of the prohead density has been removed so all the motor components can be seen.
