title: Structure and assembly of turnip crinkle virus. I. X-ray crystallographic structure analysis at 3.2 A resolution.
abstract: The structure of turnip crinkle virus has been determined at 3.2 A resolution, using the electron density of tomato bushy stunt virus as a starting point for phase refinement by non-crystallographic symmetry. The structures are very closely related, especially in the subunit arm and S domain, where only small insertions and deletions and small co-ordinate shifts relate one chain to another. The P domains, although quite similar in fold, are oriented somewhat differently with respect to the S domains. Understanding of the structure of turnip crinkle virus has been important for analyzing its assembly, as described in an accompanying paper.
