Parvoviruses have a roughly cylindrically shaped pore that surrounds each of the 12 5-fold vertices. The pore, which penetrates the virion shell, is created by the juxtaposition of 10 antiparallel beta-strands, two from each of the 5-fold-related capsid proteins. There is a bottleneck in the channel formed by the symmetry-related side chains of the leucines at position 172. We report here the X-ray crystal structure of the particles produced by a leucine-to-tryptophan mutation at position 172 and the analysis of its biochemical properties. The mutant capsid had its 5-fold channel blocked, and the particles were unable to package DNA, strongly suggesting that the 5-fold pore is the packaging portal for genome entry. ER -
