Crystal structure of a poxvirus-like zalpha domain from cyprinid herpesvirus 3.
Zalpha domains are a subfamily of the winged helix-turn-helix domains sharing the unique ability to recognize CpG repeats in the left-handed Z-DNA conformation. In vertebrates, domains of this family are found exclusively in proteins that detect foreign nucleic acids and activate components of the antiviral interferon response. Moreover, poxviruses encode the Zalpha domain-containing protein E3...
متن کاملCyprinid Herpesvirus 3
The recently designated cyprinid herpesvirus 3 (CyHV-3) is an emerging agent that causes fatal disease in common and koi carp. Since its emergence in the late 1990s, this highly contagious pathogen has caused severe financial losses in common and koi carp culture industries worldwide. In addition to its economic role, recent studies suggest that CyHV-3 may have a role in fundamental research. C...
متن کاملA poxvirus protein forms a complex with left-handed Z-DNA: crystal structure of a Yatapoxvirus Zalpha bound to DNA.
A conserved feature of poxviruses is a protein, well characterized as E3L in vaccinia virus, that confers IFN resistance on the virus. This protein comprises two domains, an N-terminal Z-DNA-binding protein domain (Zalpha) and a C-terminal double-stranded RNA-binding domain. Both are required for pathogenicity of vaccinia virus in mice infected by intracranial injection. Here, we describe the c...
متن کاملIdentification of an essential virulence gene of cyprinid herpesvirus 3
The genus Cyprinivirus consists of a growing list of phylogenetically related viruses, some of which cause severe economic losses to the aquaculture industry. The archetypal member, cyprinid herpesvirus 3 (CyHV-3) causes mass mortalities worldwide in koi and common carp. A CyHV-3 mutant was described previously that is attenuated in vivo by a deletion affecting two genes (ORF56 and ORF57). The ...
متن کاملSeasonal distribution of cyprinid herpesvirus 3 in Lake Biwa, Japan.
The seasonal distribution of the cyprinid herpesvirus 3 (CyHV-3) in Lake Biwa, Japan, was investigated. CyHV-3 was distributed all over the lake 5 years after the first outbreak. The mean concentration of CyHV-3 in water showed annual oscillation, with a peak in the summer and a trough in winter. Our results suggested that CyHV-3 is present at high density in reductive environments, such as ree...
