Promoter 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.
