Screening for Sulfolobales, their plasmids and their viruses in Icelandic solfataras
Summary We have sampled acidic springs, water and mud holes of 14 major solfataric fields of Iceland in order to isolate both heterotrophic and autotrophic members of the order Sulfolobales and toExpand
The particle SSV1 from the extremely thermophilic archaeon Sulfolobus is a virus: demonstration of infectivity and of transfection with viral DNA.
It is shown that site-specific integration is involved in establishing the lysogenic state in S. shibatae, and UV-irradiation of lysogenized S. solfataricus led to virus production apparently not accompanied by cell lysis. Expand
Picrophilus gen. nov., fam. nov.: a novel aerobic, heterotrophic, thermoacidophilic genus and family comprising archaea capable of growth around pH 0.
The morphology and physiological properties of the two species characterize Picrophilus as a novel genus that is a member of a novel family within the order Thermoplasmales. Expand
SAV 1, a temperate u.v.‐inducible DNA virus‐like particle from the archaebacterium Sulfolobus acidocaldarius isolate B12
Though a large fraction of liberated particles is found attached to structures derived from the cells, neither adsorption nor infection of a number of Sulfolobus isolates has so far been observed. Expand
The Sulfolobus-“Caldariella” group: Taxonomy on the basis of the structure of DNA-dependent RNA polymerases
The similarity of the morphology and of DNA composition, the homology of the component patterns of DNA-dependent RNA polymerases and their immunochemical crossreactivity support the conclusion thatExpand
Thermoproteales: A novel type of extremely thermoacidophilic anaerobic archaebacteria isolated from Icelandic solfataras
Two types of anaerobic extremely thermoacidophilic bacteria have been isolated from more than 50% of the samples collected in solfataric fields throughout Iceland, and the similarities in morphology and growth characteristics indicate that the two types are related to each other. Expand
Complete nucleotide sequence of the virus SSV1 of the archaebacterium Sulfolobus shibatae.
The DNA sequence of the Sulfolobus shibatae virus SSV1 is the first complete sequence of an archaebacterial virus genome and the positions of all 11 transcripts, the three characterized proteins, and the open reading frames are described. Expand
SNDV, a novel virus of the extremely thermophilic and acidophilic archaeon Sulfolobus.
A novel virus, SNDV (Sulfolobus neozealandicus droplet-shaped virus), of the crenarchaeotal archaeon Sulfol Obus is described and proposed to assign it to a novel virus family termed Guttaviridae, which is postulate a virus-encoded methylase that is active on hemimethylated DNA. Expand
Transcription in archaea: similarity to that in eucarya.
The sequences of the Sulfolobus acidocaldarius subunits D, E, and N and alignments with eucaryal homologs are presented and shows that the archaeal and eucARYal transcription systems are truly homologous and that they differ structurally and functionally from the bacterial transcription machinery.

Identification and characterization of the genes encoding three structural proteins of the Sulfolobus virus-like particle SSV1
SummaryThree structural proteins, VP1, VP2 and VP3, of the virus-like particle SSV1 of the thermoacidophilic archaebacterium Sulfolobus sp. strain B12 were purified. VP1 and VP3 are very hydrophobicExpand
