| pubmed-article:3782924 | pubmed:abstractText | The structure of the connector of bacteriophage T3 (built up by the product of gene 8) has been studied in two dimensions by combined use of translational and rotational image filtering procedures applied to tetragonal ordered aggregates of the former oligomers. This analysis, performed up to 1/1.6 nm-1 resolution, has revealed the existence of a 12-fold symmetry in the outermost region of the specimen (mainly between radii 5.2 and 6.7 nm), a 6-fold one in the inner region (between radii 1.7 and 3.2 nm), and a hole in its center. These features are very similar to the ones described for the connectors of other phages, such as T4, lambda, and phi 29, thus suggesting a common mechanism for the functions carried out by this viral region. | lld:pubmed |
