Auf Grund der Kapsomer-Zusammenlagerung kann das Kapsid eine kubische, helikale oder komplexe Symmetrie aufweisen (siehe unten). Das Kapsid schützt

Helical:contain rod shaped helical capsid which encapsulate genome Polyhedral:contains capsules in a polyhedral shape Complex: share the properties of both helical and polyhedral

Viruses are classified based on their core genetic material and capsid design. (a) Rabies virus has a single-stranded RNA (ssRNA) core and an enveloped helical capsid, whereas (b) variola virus, the causative agent of smallpox, has a double-stranded DNA (dsDNA) core and a complex capsid. According to several sources, Coronavirus is a helical virus, i.e. it should have a helical capsid.

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.

This structure folds into a helix because the protomers are thicker at one end than at the other. The diameter of the helical capsid is determined by characteristics of its protomers, while its length is determined by the length of the nucleic acid it encloses. 3) Complex- e.g., that exhibited by poxvirus and rhabdovirus. 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. Plant viruses showing helical capsid symmetry are used as a versatile platform for the presentation of multiple copies of well-arrayed immunogenic antigens of various disease pathogens.

Enveloped helical virus: These viruses consist of either DNA or RNA and capsid proteins enclosed by the phospholipid bilayer envelope and its associated proteins. Viruses use glycoproteins that are embedded in the envelope for host cell attachment.

Viral kapsid. • Viral özyapıyı çevreleyen protein tabakası. • Virüsün morfolojik yapısını belirler. • İki türlü simetrik yapı bulunur. Kübik simetri. Helikal simetri

Most of the helical viruses are enveloped and all are RNA viruses. The typical virus with helical symmetry is tobacco mosaic virus (TMV), which is a RNA virus with 2130 identical capsomeres arranged in a helix.

A capsid is the protein shell of a virus. It consists of several oligomeric structural subunits made of protein called protomers. The observable 3-dimensiona
