  2. Capsomere - Wikipedia

    en.wikipedia.org/wiki/Capsomere

    The capsomere is a subunit of the capsid, an outer covering of protein that protects the genetic material of a virus. Capsomeres self-assemble to form the capsid. [1] In this diagram of an Adenovirus, the capsid molecules are clearly visible. Subunits called protomers aggregate to form capsomeres. Various arrangements of capsomeres are: 1 ...

  3. Capsid - Wikipedia

    en.wikipedia.org/wiki/Capsid

    The capsid faces may consist of one or more proteins. For example, the foot-and-mouth disease virus capsid has faces consisting of three proteins named VP1–3. [6] Some viruses are enveloped, meaning that the capsid is coated with a lipid membrane known as the viral envelope.

  4. Dependoparvovirus - Wikipedia

    en.wikipedia.org/wiki/Dependoparvovirus

    Three proteins (VP1, VP2 and VP3) are present in each capsomere. Each capsid is made from 5 VP1, 5 VP2, and 50 VP3 proteins. The capsid does not have an envelope. [7] The genome is a single molecule of single stranded DNA with a length of 4.7 kilobases. It has only two open reading frames. The 3' open reading frame is the structural capsid ...

  5. Poliovirus - Wikipedia

    en.wikipedia.org/wiki/Poliovirus

    The three serotypes of poliovirus, PV-1, PV-2, and PV-3, each have a slightly different capsid protein. Capsid proteins define cellular receptor specificity and virus antigenicity. PV-1 is the most common form encountered in nature, but all three forms are extremely infectious. [35]

  6. Virus - Wikipedia

    en.wikipedia.org/wiki/Virus

    The capsid and entire virus structure can be mechanically (physically) probed through atomic force microscopy. [43] [44] In general, there are five main morphological virus types: Helical These viruses are composed of a single type of capsomere stacked around a central axis to form a helical structure, which may have a central cavity, or tube ...

  7. Minor capsid proteins VP2 and VP3 - Wikipedia

    en.wikipedia.org/wiki/Minor_capsid_proteins_VP2...

    The circular genome of a representative polyomavirus, WU polyomavirus, with the late region at right indicating positions of the VP1, VP2, and VP3 genes. [4]All three capsid proteins are expressed from alternative start sites on a single transcript of the "late region" of the circular viral chromosome (so named because it is transcribed late in the process of viral infection).

  8. Major capsid protein VP1 - Wikipedia

    en.wikipedia.org/wiki/Major_capsid_protein_VP1

    Major capsid protein VP1 is a viral protein that is the main component of the polyomavirus capsid. VP1 monomers are generally around 350 amino acids long and are capable of self-assembly into an icosahedral structure consisting of 360 VP1 molecules organized into 72 pentamers .
