Rhodobacter capsulatus nifA1 promoter: high-GC -10 regions in high-GC bacteria and the basis for their transcription.

abstract：:Isolated membranes of Bacillus stearothermophilus 2184D can be disrupted by treatment with sodium dodecyl sulfate (SDS). This disruption is attended by a decreased turbidity of membrane suspensions and a differential loss of activities of the electron transport system.
