Figure 3From: amiA is a negative regulator of acetamidase expression in Mycobacterium smegmatisPromoter activity assays. The fragments assayed for promoter activity are shown, with arrows indicating the direction of the fragment realtive to the β-galactosidase gene. The pAGAN construct series numbers are given below each arrow. The four identified promoter fragments (Pc, P1, P2 and P3) are labelled and indicated by thicker arrows.Back to article page
