Fig. 3From: A comparative analysis of the foamy and ortho virus capsid structures reveals an ancient domain duplicationTop hits superposed. The top two DALI hits to the full foamy virus capsid are shown as a α-carbon backbone (stereo pair) coloured using the residue similarity score calculated by SAP. (red = strong similarity, blue = none). The amino terminus of the foamy structure is marked by a large ball and the other structure is distinguished by small balls on its α-carbon atoms. a a cytoskeleton associated protein (fragment) of the arc/arg3.1 gene (PDB code: 4x3x-A), (which is thought to have originated from a Ty3/Gypsy retrotransposon family capsid) and (b) the structure of the capsid C-terminal domain of the Rous scarcoma virus (PDB code: 3g29-A)Back to article page
