Abstract excerpt
Bacteriorhodopsin, the photosynthetic protein of Halobacterium salinarum, is optimally expressed under anaerobic growth conditions. We identified Brz (OE3104F, bacteriorhodopsin-regulating zinc finger protein), a new regulator of the bop gene. It is a small protein with a zinc finger motif, encoded directly upstream of the bop gene in the same orientation. Deletion of the brz gene caused a large decrease of bop...
