  2. Coronavirus nucleocapsid protein - Wikipedia

    en.wikipedia.org/wiki/Coronavirus_nucleocapsid...

    The nucleocapsid (N) protein is a protein that packages the positive-sense RNA genome of coronaviruses to form ribonucleoprotein structures enclosed within the viral capsid. [ 2 ] [ 3 ] The N protein is the most highly expressed of the four major coronavirus structural proteins . [ 2 ]

  3. Capsid - Wikipedia

    en.wikipedia.org/wiki/Capsid

    The proteins making up the capsid are called capsid proteins or viral coat proteins (VCP). The virus genomic component inside the capsid, along with occasionally present virus core protein, is called the virus core. The capsid and core together are referred to as a nucleocapsid (cf. also virion).

  4. Nucleoprotein - Wikipedia

    en.wikipedia.org/wiki/Nucleoprotein

    Cross-sectional drawing of the Ebola virus particle, with structures of the major proteins shown and labelled on the right. Nucleoproteins tend to be positively charged, facilitating interaction with the negatively charged nucleic acid chains. The tertiary structures and biological functions of many nucleoproteins are understood.

  5. ORF9b - Wikipedia

    en.wikipedia.org/wiki/ORF9b

    ORF9b (formerly sometimes called ORF13) is a gene that encodes a viral accessory protein in coronaviruses of the subgenus Sarbecovirus, including SARS-CoV and SARS-CoV-2.It is an overlapping gene whose open reading frame is entirely contained within the N gene, which encodes coronavirus nucleocapsid protein.

  6. HBeAg - Wikipedia

    en.wikipedia.org/wiki/HBeAg

    A simplified drawing of the HBV particle and surface antigen. Purple = Lipid Envelope, Red = Nucleocapsid Core (Note: This drawing is slightly misleading in that the nucleocapsid core is a single entity even though it is depicted as a light blue icosahedral line shape and a red ring of circles). The genome organisation of HBV. The genes overlap.

  7. Viral envelope - Wikipedia

    en.wikipedia.org/wiki/Viral_envelope

    The nucleocapsid of the virion is made up of the nucleic acid and the capsid. Remember that the genomes of most viruses are very small. Genes code for instructions to make proteins, so small genomes cannot code for many proteins. Therefore, the virion capsid consists of one or only a few proteins that repeat over and over to form the structure.

  8. Hepatitis B virus - Wikipedia

    en.wikipedia.org/wiki/Hepatitis_B_virus

    HBsAg (hepatitis B surface antigen) was the first hepatitis B virus protein to be discovered. [15] It consists of small (S), medium (M) and large (L) protein. [16] HBcAg (hepatitis B core antigen) is the main structural protein of HBV icosahedral nucleocapsid and it has function in replication of the virus. [17]

  9. Zinc finger inhibitor - Wikipedia

    en.wikipedia.org/wiki/Zinc_finger_inhibitor

    This image shows the zinc finger structure of the HIV-1 nucleocapsid protein. The cysteines of the CCHC motif are given in yellow; the histidine in blue. The dashed lines represent the coordinate bonds between the Zn ion and the respective residues. NCp7 is a 55-amino acid protein that is highly basic and consists of two gag-knuckle motifs.
