SINV-1-like Viruses

Virion

Morphology:	Icosahedral
Envelope:	No
Diameter (nm):	30
Length (nm):
Structural components:	Capsid
Buoyant density (g/mL):	1.34–1.37
Buoyant density method:	CsCl
Lipid composition:	None reported
Additional information:

Genome

Nucleic acid:	RNA
Strandedness:	Single-strande
Polarity:	Positive-sense
Configuration:	Linear
Segment organization:	Segment no. 1 (kb):	9.3–10.3
	One segment(s):	9.3–10.3 (kb) total (calculated)
G + C content (%):	35–45
mRNA transcripts:
Open reading frames:	2
Additional information:	A small protein, VPg, is suggested to be linked covalently to the 5′ terminus of the viral RNA. The 3′ end is polyadenylated. Initiation of translation of the second open reading frame is mediated by internal ribosome entry site (IRES)

Replication

Entry mechanism:	Unknown
Site of transcription:
Transcriptase:
Site of genome replication:	Cytoplasm
Replicase:	Virus-encoded RNA-dependent RNA polymerase
Replication intermediate:
Site of virion assembly:	Cytoplasm
Egress mechanism:	Unknown...
