[Nucleotide sequence of the archaebacterial mobile genetic element ISH S1].

The complete primary structure (1449 b. p.) of mobile genetic element ISH S1 from Halobacterium halobium has been elucidated using the dideoxy/M13 sequencing procedure. Computer analysis of the structure reveals similarity in overall structural organization of ISH S1 and other known transposable genetic elements of halobacteria and makes it possible to propose a hypothetical model of halobacterial promoter.
