A capsid is the protein shell of a virus.It consists of several oligomeric structural subunits made of protein called protomers.The observable 3-dimensional morphological subunits, which may or may not correspond to individual proteins, are called capsomeres.The capsid encloses the genetic material of the virus.. Capsids are broadly classified according to their structure.

The helical capsid, exemplified by tobacco mosaic virus, is easiest to describe (Figure 1). The capsid is a large multimer of a single type of polypeptide enclosing the RNA genome in a groove. Protomeric units associate with one another to initially form a disk, which soon is transformed into the beginnings of a helix. The protective protein shell of each virus is called a 'capsid.' This capsid is made up of protein subunits called 'capsomeres,' which are in turn made of subunits called 'protomers.' With that in NP(Δc375) is a truncated version of the nucleocapsid protein of Newcastle disease virus (NDV) which self-assembles into a long helical structure.

Protein capsid can be arranged in different shapes. Three basic shapes are identified as helical, icosahedral or polyhedral and complex arrangement. The majority of viruses have helical or icosahedral capsid structures. Some viruses, especially bacteria infecting viruses (bacteriophages), have complicated capsid structures.

Its capsid is made from 2130 molecules of coat protein and one molecule of genomic single strand RNA, 6400 bases long. The coat protein self-assembles into the rod-like helical structure (16.3 proteins per helix turn) around the RNA, which forms a hairpin loop structure (see the electron micrograph above). 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. Nukleinsyran omges av ett skyddande proteinskal (kapsid).
