(A) Cryo-electron micrograph of  Sulfolobus turreted icosahedral virus 2, STIV2; scale bar, 100 nm. (B,C) A radially depth-cued isosurface representation of the 20-Å-resolution STIV2 reconstruction viewed down a 2-fold symmetry axis. Symmetry axes are indicated by a white ellipse (2-fold), triangle (3-fold), and pentagon (5-fold).  

 

The overall morphology of the virions (icosahedral with an internal membrane layer) resembles that of bacterial viruses from the families Tectiviridae and Corticoviridae; however, the turreted structure of the icosahedral virion is unique and the virion is built on a pseudo-T = 31 icosahedral lattice.
