Helikal kapsid

What is different about a “Poxvirus”? Helical Capsid. Helical capsids are usually formed from one protein that interlocks to form a helix-like structure around the viral genome. They are more common among viruses that infect plants, though influenza, measles, mumps, and rabies viruses all have helical capsid structures. These viruses are also negative single-strand RNA enveloped The capsid and inner genome is called the nucleocapsid. The majority of the viruses have capsids with either helical or icosahedral structure. Some viruses, such as bacteriophages , have developed more complicated structures due to constraints of elasticity and electrostatics.

Ett typiskt exempel på ett virus med helikal struktur är tobaksmosaikviruset (fig. 9.2).

Ikosaedrální (dvacetistěnová, tvaru dvacetistěnu) kapsida se skládá z dvaceti základních rovných stěn trojúhelníkovitého tvaru, které dohromady vytváří přibližně kulovitý útvar (trochu podobně jako u fotbalového míče). Helikální kapsidy mají typicky válcovitý tvar. Coronaviruses have a capsid, but it's not reminiscent of the polygonal (icosahedral) capsid depicted in the Research Gate picture you referenced. Icosahedral capsids form a sort of shell around the viral genome, where helical capsids actually bind the viral nucleic acids, holding them in a more rigid shape. A viral protein is both a component and a product of a virus.Viral proteins are grouped according to their functions, and groups of viral proteins include structural proteins, nonstructural proteins, regulatory proteins, and accessory proteins.

Engelsk definition. The outer protein protective shell of a virus, which protects the viral nucleic acid. Capsids are composed of repeating units (capsomers or capsomeres) of CAPSID PROTEINS which when assembled together form either an icosahedral or helical shape.

Helical capsids are made up of a single type of protein subunit stacked around a central axis to form a helical structure. The helix may have a hollow center, which makes it look like a hollow tube. This arrangement results in rod-shaped or filamentous virions. These virions can be anything from short and very rigid, to long and very flexible. Helical capsids are long and cylindrical.
