The sole member of this genus has been lost from collections. Therefore, the only distinguishing features are the morphological details given below.
The virions of SNDV are characterised by a "beard" of dense filaments at the pointed end of the particle (Figure 1.Guttaviridae).
See discussion under family description.
The genomic DNA of SNDV cannot be cut by many restriction endonucleases but can be cut by the dam-methylation dependent restriction endonuclease DpnI, indicating that it is extensively methylated by a dam-like methylase at the N(6) position of the adenine residue in GATC sequences [{Arnold et al., 2000:10873785RJOHTXArnold et al., 2000, SNDV, a novel virus of the extremely thermophilic and acidophilic archaeon Sulfolobus, Virology, 272, 2, 409-16}].
SNDV virions have one major capsid protein of ~ 17.5 kDa.
See description under family description.
SNDV was found in a carrier state in a Sulfolobus strain isolated from a solataric field sample in Steaming Hill, New Zealand. Virus production starts early in the stationary phase.
