Penetration of the viral genome into a host cell nucleus is critical for initiation of viral replication for most DNA viruses and a few RNA viruses. For herpesviruses, viral DNA ejection into a nucleus occurs when the capsid docks at the nuclear pore ...

Bacteriophages and their structural organisation [PDF]
Viruses are extremely small infectious particles that are not visible in a light microscope, and are able to pass through fine porcelain filters. They exist in a huge variety of forms and infect practically all living systems: animals, plants ...

HIV-1 Capsid Core: A Bullet to the Heart of the Target Cell
The first step of the intracellular phase of retroviral infection is the release of the viral capsid core in the cytoplasm. This structure contains the viral genetic material that will be reverse transcribed and integrated into the genome of infected ...

Maturation of Papillomavirus Capsids [PDF]
ABSTRACT The papillomavirus capsid is a nonenveloped icosahedral shell formed by the viral major structural protein, L1. It is known that disulfide bonds between neighboring L1 molecules help to stabilize the capsid. However, the kinetics of inter-L1 disulfide bond formation during particle morphogenesis have not previously been examined.

Apple latent spherical virus structure with stable capsid frame supports quasi-stable protrusions expediting genome release [PDF]
Picorna-like plant viruses are non-enveloped RNA spherical viruses of ~30 nm. Part of the survival of these viruses depends on their capsid being stable enough to harbour the viral genome and yet malleable enough to allow its release.

How to Assemble a Capsid [PDF]
Retroviral capsids are composed of hexagonal arrays of the viral CA protein. In this issue of Cell, Ganser-Pornillos et al. (2007) provide a molecular model of the hexagonal HIV-1 CA lattice obtained from a new electron cryomicroscopic reconstruction. This study reveals the three principal stabilizing interfaces in the capsid lattice and explains how ...

Fine-Tuning Translation Kinetics Selection as the Driving Force of Codon Usage Bias in the Hepatitis A Virus Capsid [PDF]
Hepatitis A virus (HAV), the prototype of genus Hepatovirus, has several unique biological characteristics that distinguish it from other members of the Picornaviridae family.

RNA packaging and uncoating in simple single-stranded RNA viruses [PDF]
Simple (non-enveloped) small, positive-sense single-stranded RNA viruses infect hosts from all kingdoms of life. However, their assembly and uncoating processes remain poorly understood. For turnip crinkle virus (TCV), 3D reconstructions by cryoelectron

Host-driven evolution of PCV2: insights into genetic diversity and adaptation
IntroductionsPorcine circovirus type 2 (PCV2) is a significant pathogen in swine, exhibiting notable genetic and phenotypic diversity. This study explores the evolutionary mechanisms influencing PCV2 variability, emphasizing the role of viral features ...
