Obscuruvirus (taxid:2842914)

VIRION

Unknown, discovered using viral metagenomics. Presumably enveloped.

GENOME

image

Monopartite Negative-stranded RNA linear genome about 13,7 kb.
Encodes for four proteins.

GENE EXPRESSION

Viral RNA-dependent RNA polymerase (L) binds to a promoter on each segment and transcribes a messenger RNA. Genomic RNA is possibly encapsidated by N protein.

ENZYMES

REPLICATION

NUCLEAR or CYTOPLASMIC?

  1. Virus invades host cells by unknown mechanism: genomic segments are released in cytoplasm.
  2. Transcription
  3. Replication
  4. Unknown mechanism of propagation.
