Comparison of AS-protease promoter with other promoter sequences. A probable promoter regions (-35, -10 region) and a Shine-Dalgarno (SD) region is shown by solid lines and is highlighted. Bacilli protease promoter represents, Bacillus stearothermophilus protease promoter. Protease promoter represents the predicted alkaline serine protease promoter region. E. coli protease promoter represents, E.coli lon protease promoter.
