Two shapes of viral capsids
WebTypically, viral capsids come in different shapes that tend to be unique for each virus in vivo (see Fig. 1), but that can be changed by the assembly conditions in vitro. WebMay 24, 2024 · Pores provide controlled permeability of molecules based on their physical properties such as size, charge, and chemical makeup. For example, carboxysomes are proteinaceous compartments found within bacterial cells and architecturally resemble icosahedral virus capsids. 2 The porous shell controls diffusion across and is thought to …

WebViral capsids are the protein cage derived from the protein shell of a virus, and can have different shapes, sizes, and protein subunits, depending on the virus type [101]. The … WebThese capsids somewhat resemble a soccer ball. Both helical and polyhedral viruses can have envelopes. Viral shapes seen in certain types of bacteriophages, such as T4 phage, and poxviruses, like vaccinia virus, may have features of both polyhedral and helical viruses so they are described as a complex viral shape (see Figure 6.6).
