Genus: Sakobuvirus


Genus: Sakobuvirus

Distinguishing features

The genus is distinguished on the basis of genetic characters.

Virion

Morphology

No details are available on the morphology of the virions.

Nucleic acid

Genome (Ng et al., 2014): c. 7,800 nt (5′ UTR: 591 nt; ORF: 7,059 nt; 3′-UTR: 157 nt). 5′-UTR contains a predicted type IV IRES. The location of the cre has not been identified.

Genome organization and replication

Genome layout:

VPg+5′-UTRIRES-IV-[L/1AB-1C-1D/2AH-Box/NC-2B-2C/3A-3B-3C-3D]-3′-UTR-poly(A)

The deduced polyprotein is of 2,352 amino acids. There is a L protein with unknown function. 1AB remains uncleaved. 2A protein has a H-box/NC sequence motif.

Antigenicity

See discussion under family description.

Biology

Viral RNA was detected in faeces of apparently healthy cats. Partial sequences of sakobu-like viruses were obtained from faecal samples of fur seals (Kluge et al., 2016).

Species demarcation criteria

There is only a single species in the genus.
