Formation of empty B19 parvovirus capsids by the truncated minor capsid protein

Journal of Virology, 1994
We previously reported that empty capsids of B19 parvovirus were formed by the major capsid protein (VP2) alone expressed in a baculovirus system, but the minor capsid protein (VP1), longer by 227 amino acids, alone did not form empty capsids. We report here further investigations of the constraints on capsid formation by truncated versions of VP1 ...

Modifying Filamentous Phage Capsid: Limits in the Size of the Major Capsid Protein

Journal of Molecular Biology, 1995
Ff filamentous phages are long thin cylindrical structures that infect bacteria displaying the F pilus and replicate without lysing the host. These structures are exploited to display peptides by fusing them to the amino terminus of either the bacterial receptor protein (pIII) or the major coat protein (pVIII).

A minor capsid protein P30 is essential for bacteriophage PRD1 capsid assembly

Journal of Molecular Biology, 2001
Bacteriophage PRD1 is a double-stranded DNA virus infecting Gram-negative hosts. It has a membrane component located in the interior of the isometric capsid. In addition to the major capsid protein P3, the capsid contains a 9 kDa protein P30. Protein P30 is proposed to be located between the adjacent facets of the icosahedral capsid and is required for

Capsid Protein-Encoding Genes of Hamster Polyomavirus and Properties of the Viral Capsid

Virus Genes, 1999
On the basis of its genome organization the hamster polyomavirus (HaPV) is closely related to the murine polyomavirus Py. But HaPV infection, in contrast to Py infection, gives rise to two different tumor types; depending on the hamster strain used for infection, HaPV induces either epitheliomas or lymphomas.

Role of Capsid Proteins

2008
Coat proteins (CPs) of all plant viruses have an early function in disassembly of parental virus and a late function in assembly of progeny virus. Depending on the virus, however, CPs may play a role in many steps of the infection cycle in between these early and late functions.

Capsid proteins of simian virus 40

Biochemical and Biophysical Research Communications, 1970
Abstract Purified SV40 virions were disrupted by sodium dodecyl sulfate (SDS), β-mercaptoethanol and heat, and the proteins analyzed in polyacrylamide gels in the presence of SDS. Six different polypeptide chains were found. Agregation of proteins was ruled out by treatment with 8 M urea. The major protein had a molecular weight (M.

Theoretical studies of viral capsid proteins

Current Opinion in Structural Biology, 2000
Recent results in structural biology and increases in computer power have prompted initial theoretical studies on capsids of nonenveloped icosahedral viruses. The macromolecular assembly of 60 to 180 protein copies into a protein shell results in a structure of considerable size for molecular dynamics simulations. Nonetheless, progress has been made in

Retrovirus Capsid Protein Assembly Arrangements

Journal of Molecular Biology, 2003
During retrovirus particle assembly and morphogenesis, the retrovirus structural (Gag) proteins organize into two different arrangements: an immature form assembled by precursor Gag (PrGag) proteins; and a mature form, composed of proteins processed from PrGag.

Genetic variability in the sapovirus capsid protein

Virus Genes, 2006
Sapovirus (SV), which causes gastroenteritis in humans, is composed of genetically divergent viruses classified into 5 genogroups. In this study, 2.2-kb nucleotide sequences of the 3' terminus of the genome of 15 SV strains detected in Japan were determined. The 15 SV strains could be classified into four genogroups (GI, GII, GIV and GV), and in two of

The Major Capsid Protein of the Lipid-Containing Bacteriophage PR4 Is the Precursor of Two Other Capsid Proteins

Virology, 1994
We report that capsid proteins P16 and P18 of bacteriophage PR4 are synthesized by post-translational processing of a portion of the major capsid protein, P2. A polyclonal antibody raised against purified P2 reacted with P16 and P18 as well as with P2. A monoclonal antibody reacted with both P2 and P18.
