Packaging signals in single-stranded RNA viruses: nature’s alternative to a purely electrostatic assembly mechanism [PDF]
, 2013 The formation of a protective protein container is an essential step in the life-cycle of most viruses. In the case of single-stranded (ss)RNA viruses, this step occurs in parallel with genome packaging in a co-assembly process.

Capsid protein sequence diversity of chicken astrovirus [PDF]
Avian Pathology, 2012 The complete capsid gene sequences of 24 chicken astroviruses (CAstVs), collected in the UK, Germany, the Netherlands and South Africa from the 1980s to 2008, were determined and compared with that of a US CAstV (UGA-2006). Pairwise comparisons and phylogenetic analysis demonstrated the existence of two major capsid groups, designated A and B, which ...

Evolutionary Assembly and Future Design of Gibberellin Signaling
Advanced Science, EarlyView.ABSTRACT Gibberellin (GA) signaling is widely regarded as a canonical hormone‐controlled growth pathway, yet accumulating evidence suggests that it emerged through stepwise evolutionary assembly rather than as a pre‐formed regulatory system. Here, we revisit the origin and diversification of the GA pathway from an evolutionary perspective.

The effect of chemical chaperones on the assembly and stability of HIV-1 capsid protein. [PDF]
PLoS ONE, 2013 Chemical chaperones are small organic molecules which accumulate in a broad range of organisms in various tissues under different stress conditions and assist in the maintenance of a correct proteostasis under denaturating environments.

Measuring the force ejecting DNA from phage [PDF]
, 2004 We discuss how a balance can be established between the force acting to eject DNA from viral capsids and the force resisting its entry into a colloidal suspension which mimics the host cell cytoplasm.

Venezuelan Equine Encephalitis Virus Capsid—The Clever Caper
Viruses, 2017 Venezuelan equine encephalitis virus (VEEV) is a New World alphavirus that is vectored by mosquitos and cycled in rodents. It can cause disease in equines and humans characterized by a febrile illness that may progress into encephalitis.

pH dependence of charge multipole moments in proteins
, 2017 Electrostatic interactions play a fundamental role in the structure and function of proteins. Due to ionizable amino acid residues present on the solvent-exposed surfaces of proteins, the protein charge is not constant but varies with the changes in the ...

Assembly and Translocation of Papillomavirus Capsid Proteins [PDF]
Journal of Virology, 2002 ABSTRACT The major and minor capsid proteins of polyomavirus are preassembled in the cytoplasm and translocated to the nucleus only as a VP1-VP2/VP3 complex. In this study, we describe independent nuclear translocation of the L1 major protein and the L2 minor capsid protein of human papillomavirus type 33 by several approaches.
