The mass of the Sindbis virus nucleocapsid suggests it has T = 4 icosahedral symmetry

The mass of the nucleocapsid of the alphavirus Sindbis was determined by scanning transmission electron microscopy. The nucleocapsid was found to have an average mass of 10.54 × 10 6 Da with the largest percentage of particles showing a mass of 10.7 to 10.9 × 10 6 Da. These data predict that the nuc...

Zusammenfassung:The mass of the nucleocapsid of the alphavirus Sindbis was determined by scanning transmission electron microscopy. The nucleocapsid was found to have an average mass of 10.54 × 10 6 Da with the largest percentage of particles showing a mass of 10.7 to 10.9 × 10 6 Da. These data predict that the nucleocapsid contains 240 copies of protein and is a T = 4 icosahedron.
