Summary Three different temperent viruses of the extremely thermophilic chemolithoautotrophic archaebacterium, Thermoproteus tenax, TTV1, TTV2 and TTV3, each contain linear, double-stranded DNA, TTV1 and TTV2 of 16 kb, TTV3 of 27 kb. They are oblong and each consists of an outer envelope and an inner core associated with the DNA. TTV1 contains four major proteins, an envelope of unknown nature and non-protein material linked to two of the proteins in non-covalent manner. The 5′-ends of the DNA are protected by hydrophobic ligands. The viruses have neither homologies with each other nor with the host. Lysogens are induced upon sulfur depletion during autotrophic growth. Alternatively, sensitive, non-lysogenic cells allow lytic multiplication.
