Kurzbeschreibung (Abstract)

Southern blot analysis and nucleotide sequencing of DNA from three bacterio-opsin-deficient mutants of the archaebacterium Halobacterium halobium (M86, W105, and W109) revealed that they each contain an alteration in a region 2,000 to 3,800 base pairs (bp) upstream of the bacterio-opsin gene (bop). Nucleotide sequence analysis of this region, which is also located downstream of the previously characterized brp gene, revealed that it contains an open reading frame (ORF) of 2,022 bp. This 2,022-bp ORF has a start codon which overlaps the stop codon of the brp gene and is read in the same direction. The ORF could encode an acidic protein of 73,334 daltons (674 amino acids) with a predicted secondary structure typical of a soluble protein. Bop mutant M86 contains a 1,883-bp deletion extending from bp 351 of the ORF, to 197 bp beyond the stop codon. Mutant W105 has an ISH2 element integrated at bp 1239 of the ORF, and mutant W109 has an ISH26 element integrated at bp 1889. Our results suggest that the ORF is a gene (designated bat for bacterio-opsin activator gene) involved in bop gene expression.
