The capsomere and nucleic acid are wined together to form helical or spiral tube like structure. 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. Protein capsid can be arranged in different shapes.

Virus – Wikipedia

Hepatitis B is a small enveloped DNA virus that poses a major hazard to human health. The crystal structure of the T = 4 capsid has been solved at 3.3 A resolution, revealing a largely helical protein fold that is unusual for icosahedral viruses. Figure 1.

Helical capsids are usually flexible and rodlike. The length of the helical capsid is usually determined by the length of the nucleic acids, that is, some defective interfering (DI) viruses having shorter nucleic acids will have a shorter helical nucleocapsid (e.g., DI RNA of VSV). A capsid is the protein shell of a virus, enclosing its genetic material. 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 proteins making up the capsid are called capsid proteins or viral coat proteins.

A packed bed anion exchange chromatography (PB-AEC), SepFastTM Supor Q pre-packed column, was used to purify NP(Δc375) from clarified feedstock. Helical capsid: The capsids with helical symmetry are filamentous in nature. The capsid appears like a long tube with the genome inside it. The capsid appears like a long tube with the genome inside it. Figure 1. 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.
