Portal protein

Function The portal protein (PP) is a key component during viral chromosomal packaging. PPs have a central channel through which DNA movements occur. PPs are proposed to be the mechanical device that pumps DNA to the interior of the viral capsid. The DNA translocation motor is composed of PP and of the the viral ATPase that fuels DNA translocation. The PP has an active control over the viral ATPase activity. 3D Structures of portal protein Portal protein 3D structures
