Smacoviridae is a family of single-stranded DNA viruses.[1] The genomes of this family are small (2.3–2.8 kilobases in length). The name Smacoviridae stands for 'small circular genome virus'.[2] The genomes are circular single-stranded DNA and encode rolling-circle replication initiation proteins (Rep) and unique capsid proteins. As of 2021, 12 genera and 84 species are recognized in this family.[3][4] The viruses in this taxon were isolated from faecal samples from insects and vertebrates by metagenomic methods. Little is known about their biology.
Taxonomy[edit]
The family Smacoviridae is the sole member of the order Cremevirales and together with other families of CRESS DNA viruses is included within the phylum Cressdnaviricota.[5]
The family currently includes the following genera:[3][4]
- Babosmacovirus
- Bonzesmacovirus
- Bostasmacovirus
- Bovismacovirus
- Cosmacovirus
- Dragsmacovirus
- Drosmacovirus
- Felismacovirus
- Huchismacovirus
- Inpeasmacovirus
- Porprismacovirus
- Simismacovirus
Biology[edit]
These viruses have single stranded genomes of 2.3–2.8 kilobases in length. The genome encodes two proteins, a Rep (replicator) and a CP (capsid) protein.[citation needed]
