A small basic protein from the brz-brb operon is involved in regulation of bop transcription in Halobacterium salinarum

摘要

BackgroundThe halophilic archaeon Halobacterium salinarum expresses bacteriorhodopsin, a retinal-protein that allows photosynthetic growth. Transcription of the bop (bacterioopsin) gene is controlled by two transcription factors, Bat and Brz that induce bop when cells are grown anaerobically and under light.
