A Viral Biorealm page on the family Kashmir Bee Virus
Baltimore Classification
Group IV: (+) sense single-stranded RNA viruses
Higher order categories
Order: Picornavirales
Family: Dicistroviridae
Genus: Cripavirus
Description and Significance
Genome Structure
The KBV genome is composed of (+) sense ssRNA and is 9506 nt in length. The genome contains two open reading frames each coding for a polyprotein. These ORFs are separated by and intergenic region and flanked with short non coding regions.
The 5’ ORF codes the non-structural polyprotein which includes three helicase domains, a 3C-protease domain, and 8 RNA polymerase domains (including and RNA-dependent RNA polymerase). The 3’ ORF codes for the structural polyprotein which contains two picornavirus-like capsid protein domains.
Virion Structure of Kashmir bee virus
The KBV virion consists of a non-enveloped, icosohedral capsid. The capsid is constructed from 3 structural proteins. The capsid appears round and is approximately 30 nm in width.
